In order to minimize harmful effect of synthetic dye (direct yellow and direct violet) the capacity of Zn/Al, Zn/Cr and Zn/Fe layered double hydroxides of these contaminant was studied in this work. Batch adsorption experiment was conduct to investigate the effect of various operating parameters such as contact time, initial dye concentration and adsorption temperature in order to provide optimal condition in removal synthetic dye. Based on result, the sorption of direct dye onto LDHs followed pseudo-second-order rate model. The equilibrium adsorption data for both direct dye was fitted Freundlich isotherm model

Layered double hydroxides are composed by substitution of metal cation divalent and trivalent. Metal cation divalent and trivalent can be changed. In this work, effect metal cation trivalent (M3+) toward layer formation were studied. Synthesis of LDHs has used co-precipitation methods with molar ratio 3:1 and kept pH at 10. The result of synthesis was characterized by X-ray Diffraction (XRD) and Fourier Transform Infrared (FT-IR) analyses.

Layered double hydroxides Mg/Al and Ca/Al has been synthesized by co-precipitation method with molar ratio M2+:M3+ (3:1) at pH 10. The synthesized materials were characterized by XRD and FTIR. The materials were used as adsorbent for the removal Cobalt (II) in aqueous solution. The adsorption experiments were studied through some variables adsorption such as variation of contact time, variation of temperature and variation of initial concentration. Kinetic parameters was obtained from variation of contact time. Data was analyzed by pseudo-first-order and pseudo-second-order kinetics models in linear analyses. The kinetic studies showed that the adsorption process more fitted by pseudo-second-order than pseudo-first-order based on coefficient correlation. Isotherm parameters was calculated using Langmuir and Freundlich isotherm models. The adsorption process was spontaneous and endothermic.

Modification of Cu/Cr layered double hydroxides (LDHs) has been conducted by intercalation using Keggin type polyoxometalate [a-SiW12O40]4- to form CuCr-[a-SiW12O40]. The materials were analyzed by XRD, FTIR, and surface area analyses. Furthermore, materials were used as selectivity adsorbents of cationic dyes such as malachite green, rhodamine-B and methylene blue. The malachite green is more selective than others from an aqueous solution. The adsorption of malachite green showed that the adsorption capacity of CuCr-[a-SiW12O40] was higher than pristine LDHs. The adsorption process was followed pseudo second order kinetic model and Langmuir isotherm adsorption. The Qmax value of CuCr-[a-SiW12O40] reached 55.322 mg/g at 323 K after 100 minutes adsorption time. Thermodynamic parameters such as ΔG, ΔH and ΔS confirm that the adsorption process was endothermic, spontaneous, and more favorable at high temperatures. The intercalated material was higher structural stability toward reusability adsorbent than pristine LDHs.

This research explores the potential of locally sourced natural zeolite from the Tanggamus District, Indonesia, for the removal of ammonium from shrimp pond wastewater. The study utilizes a comprehensive approach involving desilication modification, batch adsorption experiments, and field-scale application. The zeolite, predominantly composed of clinoptilolite, undergoes calcination at varying temperatures, with 200°C proving to be optimal for enhancing ammonium adsorption capacity. The study also highlights the efficient use of zeolite at a lower dosage of 5 g/L, yielding high removal efficiency. The real-world effectiveness of this method was confirmed by field experiments, where the application of calcined zeolite resulted in lower ammonium concentrations in shrimp ponds. The results demonstrate that the application method, specifically direct spreading in the ponds, affects adsorption performance. These findings underscore the potential of using Tanggamus Natural Zeolite as a cost-effective and eco-friendly solution for ammonium control in shrimp pond wastewater. This work paves the way for future research focusing on the long-term application effects and zeolite regeneration methods to further improve the economic and environmental efficiency of this approach.

The environmental concern related to excessive ammonium in water bodies necessitates efficient and cost-effective removal techniques. This study investigated the modification of natural zeolite collected from the Tanggamus district of Lampung Province, Indonesia, with ethylenediaminetetraacetic acid (EDTA) to enhance its performance for ammonium adsorption from aqueous solution. The modified and natural zeolites were characterized using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), N2 adsorption-desorption isotherm, and scanning electron microscopy (SEM). Results indicated that the modification did not cause significant structural changes but increased the mesoporosity of the zeolites, which was beneficial for ammonium adsorption. The adsorption studies revealed that the EDTA modified zeolites consistently outperformed the natural zeolite and that the adsorption process was exothermic in nature. The Langmuir and Freundlich isotherm models fit the adsorption data well, indicating that the adsorption process occurs on both homogenous and heterogeneous surfaces. Thermodynamic studies confirmed that the adsorption process was exothermic and that the EDTA modification increased the spontaneity of the ammonium adsorption process. Overall, this study highlights the potential of EDTA-modified zeolites as an effective material for ammonium removal from aqueous solutions.

The persistent presence of organic dyes like Congo Red (CR) in wastewater poses a significant environmental challenge. In this study, CeO2 nanofibers (CeO2-NF) were successfully synthesized via electrospinning followed by calcination as potential photocatalysts for the degradation of CR pollutants in aqueous solutions. The synthesized nanofibers were characterized using field emission scanning electron microscopy coupled with energy dispersive X-Ray Spectroscopy (FESEM-EDS) for morphological and elemental analyses, X-Ray Diffraction (XRD) for crystalline structure, and Fourier transform infrared (FTIR) spectroscopy for molecular properties. Photocatalytic degradation experiments were conducted under UVC light irradiation, with the CeO2-NF1, CeO2-NF2, and CeO2-NF3 samples achieving CR degradation percentages of 95.6%, 96.9%, and 95.2%, respectively, after 130 minutes of reaction time. Kinetic analysis revealed that the photocatalytic degradation followed pseudo-first-order kinetics, with rate constants of 0.020 min-1, 0.024 min-1, and 0.025 min-1 for CeO2-NF1, CeO2-NF2, and CeO2-NF3, respectively, highlighting the superior performance of CeO2-NF3. These results indicate that CeO2NF could serve as an effective material for the photocatalytic degradation of organic dyes, offering a promising approach for wastewater treatment applications.

The presence of antibiotics in aquatic environments poses significant environmental and health risks, requiring advanced treatment strategies for their removal. In this study, we report the straightforward hydrothermal synthesis of high surface area ortho-Nb2O5 and its dual role as both an adsorbent and photocatalyst for the removal of tetracycline (TC) from wastewater. The structural and morphological properties of ortho-Nb2O5 were systematically investigated using XRD, FTIR, FESEM-EDS, and BET surface area analysis. The ortho-Nb2O5 synthesized at 72 hours (Nb2O5_72) exhibited a high BET surface area of 242.42 m2/g, mesoporosity, and a bandgap of 3.28 eV, enabling efficient UV-driven photocatalysis. Adsorption studies revealed a high TC removal capacity of 32 mg/g at equilibrium. Under UV irradiation, ortho-Nb2O5 achieved significant photocatalytic degradation of TC.
