Abstract

Modification of the layered double hydroxide of CuAl-LDHs by composite with hydrochar (HC) to form CuAl-HC LDH. Material characterization by XRD, FT-IR and SEM analysis was used to prove the success of the modification. The characterization of XRD and FT-IR spectra showed similarities to pure LDH and HC. Selectivity experiments were carried out by mixing malachite green, methylene blue, rhodamine-B, methyl orange, and methyl red to produce the most suitable methyl blue dye for CuAl-LDH, HC and CuAl-HC adsorbents. The effectiveness of CuAl-HC LDH as adsorbent on methylene blue adsorption was tested through several influences such as adsorption isotherm, thermodynamics, and adsorbent regeneration. CuAl-HC LDH adsorption isotherm data shows that the adsorption process tends to follow the Langmuir isotherm model with a maximum adsorption capacity of 175.439 mg/g with a threefold increase compared to pure LDH. The effectiveness of the adsorbent for repeated use reaches five cycles as evidenced by the maximum capacity regeneration data reaching 82.2%, 79.3%, 77.9%, 76.1%, and 75.8%.

Abstract

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.

Abstract

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.

Abstract

Mg/Cr layered double hydroxide (LDH) was prepared and modified using an intercalation of oxalate anions ((COO)22-) to form Mg/Cr-(COO)22. The materials were then investigated to malachite green removal to determine the adsorption ability. Furthermore, the desorption process and regeneration of adsorbent were systematically conducted. The adsorption of green malachite on Mg/Cr- LDH and Mg/Cr-(COO)22- materials fitted to the pseudo-second-order (PSO) kinetic model and Freundlich isotherm model with an adsorption capacity of 33.784 mg/g (333K) for Mg/Cr LDH and 64.516 mg/g (333K) for Mg/Cr-(COO)22-. Thermodynamic data showed that the adsorption process was spontaneous and endothermic. Also, the appropriate reagent desorption study was found as hydrochloric acid and material regeneration studies exhibited a good recycling performance after 3 times cycles and, the Mg/Cr-oxalate showed a good performance for malachite green adsorption. It can be concluded that Mg/Cr--(COO)22- can adsorb the dye stuffs effectively.

Abstract

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.

Abstract

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.
