Abstract

This study aims to synthesize the NiAl-LDH/K4[α-SiW12O40] composite using the coprecipitation method and evaluate its ability to adsorb Cr(VI) from aqueous solutions. The material characterization showed a significant increase in the specific surface area of the composite compared to pure NiAl-LDH, contributing to an enhanced Cr(VI) adsorption capacity. XRD and FT-IR results confirmed the successful synthesis and integration of K4[????-SiW12O40] into the NiAl-LDH structure. At the same time, BET analysis indicated that the specific surface area of the composite doubled compared to pure NiAl-LDH. The adsorption kinetics data indicated that the adsorption process followed the Pseudo-Second-Order (PSO) model with an R2 value close to 1, suggesting the dominance of chemisorption in the Cr(VI) adsorption mechanism. Isotherm analysis showed that the Freundlich model was more suitable than the Langmuir model, indicating that adsorption occurred on a heterogeneous surface with multilayer formation. The Cr(VI) adsorption capacity of the NiAl-LDH/K4[α-SiW12O40] composite reached 17.123 mg/g, higher than that of pure NiAl-LDH at 188.68 mg/g. The Cr(VI) adsorption process involved chemical interactions between Cr(VI) and functional groups on the adsorbent surface, complex formation, and precipitation.

Abstract

Pollution from dyes is well-known for its harmful effects on human health and the environment. Eliminating pollutants such as dyes is a crucial task that can be achieved through various methods, one of which is adsorption. The synthesis of graphene oxide material is achieved from graphite using the Hummers method. The obtained material was then characterised using XRD and FT-IR techniques and tested as an adsorbent for selective adsorption of anionic dyes. The obtained results indicate that the congo red dye was absorbed the most in the selective dyes process, followed by the methyl orange dye, and finally the direct yellow dye.

Abstract

The removal of hazardous anionic dyes from wastewater is a critical environmental challenge due to their toxic effects and persistence in aquatic systems. This study investigates the adsorption performance of a new composite material, consisting of MgAl layered double hydroxide (LDH) and Lignin (MgAl LDH/Lignin), to remove three different anionic dyes: congo red, direct yellow, and procion red. The composite material was synthesized and thoroughly examined using various techniques, including X-ray diffraction, Fourier transform infrared spectroscopy, Brunauer-Emmett-Teller, and Barrett-Joyner-Halenda. The adsorption isotherm studies indicate that the adsorption of congo red and procion red onto the MgAl LDH/Lignin composite follows the Langmuir isotherm model, suggesting a monolayer adsorption on a uniform surface. On the other hand, the adsorption of direct yellow conforms to the Freundlich isotherm model, indicating the possibility of multiple layers being adsorbed on a surface with varying properties. The maximum adsorption capacities for congo red, direct yellow, and procion red were found to be 75.76 mg/g, 51.55 mg/g, and 74.63 mg/g, respectively. The results of this study demonstrate the promising capabilities of MgAl LDH/Lignin composites as highly efficient adsorbents for the treatment of wastewater contaminated with anionic dyes. This research provides valuable insights into the potential of these composites to address the pressing issue of water pollution in a sustainable manner.

Abstract

The intercalation of of Ca/Al layered double hydroxide (LDH) has been successfully conducted into using several intercalants with different size compounds after termal treatment process to reconstruct structure of Ca/Al LDH. Ca/Al LDH was synthesized by co-precipitation at pH 11 then calcination at various temperatures following with intercalation using water, sodium hydroxide, sodium carbonate and Keggin type of polyoxometalate K4[α-SiW12O40]. Characterization of Ca/Al LDH was carried out by XRD and FTIR analyses. XRD analysis showed that unique diffraction peak of Ca/Al LDH at 10o with interlayer space 4.67 Å. Gradual thermal treatment of Ca/Al LDH was achieved until loss unique diffraction peak at temperature 700 oC to form shrinking layer. Intercalation of water, sodium hydroxide, sodium carbonate, and polyoxometalate to shrink layer of Ca/Al LDH can create formation of well crystalline LDH to reconstruct layer structure with formation of unique diffraction at 10◦. The interlayer distance of Ca/Al LDH was increased after intercalation process. Thus reconstruction structure of LDH was successfully conducted with flexibility of layer.

Abstract

Heavy metals in the environment can have a detrimental impact on human health. This study successfully used a new adsorbent material, specifically layered double hydroxide pillared with keggin polyoxometalate H4[α-PW12O40]•nH2O (Ca-Al/POM), to effectively remove cadmium (II) from aqueous solution. The Ca-Al/POM adsorbent has been thoroughly analyzed using X-ray diffraction and FT-IR. The findings showed an increase in the maximum adsorption capacity for cadmium (II) when using Ca-Al LDH intercalated with POM. The study of equilibrium adsorption isotherms showed that the Ca-Al/POM adsorbent effectively removed cadmium (II) and fit the Freundlich isotherm model. In addition, the adsorption kinetics study showed that the adsorption of cadmium (II) on Ca-Al/POM followed a pseudo second-order kinetics model.

Abstract

In order to ensure the availability of pure water free from contaminants, we focused on developing different laboratory-made filters and applying the ready-made nanosilver type Ag1 and the prepared type Ag2 prepared in the laboratory and loading them on the filters. We evaluated their effectiveness in removing and inhibiting bacteria based on the filter type and pore size, and we observed an increase in inhibition efficiency. In addition, we subjected the samples to UV testing within the wavelength range of 200-800, which is the range of nanosilver. We used EDX to confirm the presence of nanosilver in the samples. AFM examination, which shows the surface roughness values, pressure and grain size distribution of the prepared particles, and SEM examination, which shows the particle distribution, shapes and size measurement. To verify the stability of Nano silver and its strong negativity and confirm its size, a Zet test was performed to determine the negativity of the material and the nano size. The resulting water was analyzed with a TDS device to measure the dissolved salts in the water resulting from the different manufactured filters and to evaluate the drinking water and ensure that it is within acceptable levels. Then we used the Atomic Assay (AAS) to measure the percentage of nano silver in the drinking water resulting from the prepared filters and that the silver present does not affect the water because its percentage is very small and the silver loaded on the different filters has a moderate toxicity percentage that does not affect the water.

Abstract

In this research, zinc nanoparticles were prepared using pulsed laser ablation in liquids. A pulsed Nd+:YAG laser with wavelength (532 nm) was applied to a pure zinc target immersed in deionized water, and the structural and optical properties of the prepared zinc nanoparticles were studied. The behavior of the UV absorption spectra of zinc nanoparticles was studied as a function of pulse number and ablation energy. The UV-vis absorption spectra showed absorption peaks in the ultraviolet region and in the visible region, the latter being responsible for the formation of zinc nanoparticles, and an increase in the intensity of the absorption peaks with increasing number of laser pulses was observed. Scanning electron microscopy results measured after examining drops of zinc nanoparticle solution showed that the nanoparticles were predominantly spherical in shape with nanoparticle sizes ranging from (42.49, 42.42, and 39.31 nm) respectively, and decreasing in size with increasing ablation pulses, with the best results at higher ablation pulses, the formation of zinc nanoparticles was confirmed by infrared spectroscopy, which confirmed the formation of nanoparticles.

Abstract

This study successfully prepared longan peel hydrochar via hydrothermal carbonization, characterized and evaluated for its adsorption capacity of cationic dyes malachite green (MG) and rhodamine B (RhB) in aqueous solution. Material characterization through XRD analysis revealed diffraction peaks indicative of carbonaceous content, supported by FTIR results showing OH, C-O, and C-O-C functional groups. The BET analysis showed a surface area of 18.712 m2/g, and SEM images displayed a heterogeneous, irregular surface morphology with spherical particles. The longan peel hydrochar exhibited adsorption capacities of 117.647 mg/g for MG and 50.505 mg/g for RhB, with MG showing greater selectivity, as demonstrated through dye mixture adsorption tests. The adsorption process was spontaneous, endothermic, and conformed to the pseudo-second-order kinetic model. Adsorption of MG followed the Freundlich isotherm, while RhB adsorption conformed to the Langmuir isotherm. Additionally, the hydrochar exhibited reusability for up to two adsorption cycles, indicating its potential as an effective adsorbent for cationic dye removal from aqueous solutions.

Abstract

This study investigates the adsorption characteristics of phenol on rice husk biochar (BC) and microcrystalline cellulose (MC), with a focus on their structural, kinetic, isotherm, and thermodynamic properties. XRD and FTIR analyses reveal that BC and MC possess similar carbon-based structures. Nitrogen adsorption-desorption isotherms highlight BC’s higher surface area and pore volume, which likely contribute to its superior adsorption performance. Adsorption kinetics are best described by the PSO model, indicating chemisorption as the rate-limiting step. Isotherm studies show that the Langmuir model provides a better fit, suggesting monolayer adsorption on homogeneous surfaces. Thermodynamic parameters indicate that phenol adsorption onto BC is endothermic and spontaneous, with adsorption capacity increasing with temperature, while MC shows minimal temperature sensitivity. The adsorption capacity of phenol using BC and MC was obtained as 28.50 mg/g and 13.25 mg/g, respectively. The reusability tests reveal that BC retains significant adsorption capacity over multiple cycles compared to MC. Overall, BC is identified as a more efficient and reusable adsorbent for phenol removal in aqueous solutions.

Abstract

This study investigates the effectiveness of ZnAl-LDH modified with polyoxometalate (POM) as an adsorbent material in the competitive adsorption of heavy metal ions Cr(VI) and Fe(II). The material was synthesized using the co-precipitation method, resulting in ZnAl-LDH@POM with enhanced interlayer spacing, a specific surface area 14 times more significant, and increased surface-active sites. Characterization using XRD, FT-IR, and BET confirmed the successful structural modification and improved adsorption properties. Kinetic studies revealed that adsorption followed a pseudo-second order kinetic model, achieving maximum efficiency within 50 minutes. Isothermal analysis demonstrated maximum adsorption capacities (???????????????? ) of 92.95 mg/g for Fe(II) and 44.44 mg/g for Cr(VI). These findings highlight the potential of ZnAl-LDH@POM as an effective adsorbent for treating heavy metal-contaminated wastewater.
