Summary: This study investigated the potential advantage of ZnFe2O4-incorporated activated carbon (ZFAC) in the removal of cationic dye crystal violet (CV) from aqueous solutions. The results showed that ZFAC had a high adsorption capacity at optimal pH, temperature, and CV concentration, and the adsorption process followed the Langmuir isotherm model. Thermodynamic analysis indicated that the adsorption was spontaneous, endothermic, and a random process, supporting a physical adsorption mechanism.

Summary: A cationic starch intercalated montmorillonite adsorbent was developed for the removal of basic dyes from aqueous solution. The adsorption capacity increased with decreasing cationic groups in the starch or increasing the mass ratios of montmorillonite to starch. Adsorption behavior followed the Langmuir isotherm.

Summary: In this study, chitosan-treated nanocomposite was used as an effective adsorbent to remove methyl orange dye from contaminated water. The introduction of chitosan improved the adsorption capacity and rate effectively, and the nanocomposite adsorbent exhibited high reusability. Therefore, chitosan-based fibrous nanocomposite adsorbent is expected to become one of the best candidate materials for future industrial wastewater treatment.

Summary: The study involved the preparation of chemically modified lignin and alginate hybrid adsorbents for efficient removal of cationic dyes. The encapsulation of carboxylated lignin into alginate beads resulted in higher methylene blue removal capacity due to the introduction of carboxylated anions. The Alg/C-Lig beads exhibited a high monolayer maximum adsorption capacity and stable adsorption efficiency even after multiple adsorption/desorption cycles, making them a promising candidate for dye wastewater purification.

Summary: The food industry generates significant amounts of organic waste, and incorrect disposal can have negative environmental and economic impacts. The jaboticaba peel is a widely-used organic waste in the industry due to its sensory characteristics. This study developed a low-cost adsorbent material, using chemically activated residues from jaboticaba bark, for the removal of the cationic dye methylene blue. The results showed that the chemically activated jaboticaba bark had the highest adsorption capacity and can be a sustainable alternative for water decontamination.

Summary: This work investigated the adsorptive removal of cationic dyes using carbonaceous materials and found that oxidatively functionalized metal-organic framework (MOF)-derived carbons showed remarkable performance in the adsorption of small cationic dyes. However, they were not effective in adsorbing anionic dyes and large cationic dyes. This study reveals the potential application of modified carbonaceous materials in dye adsorption.

Summary: The nanocomposite composed of magnetic nanoparticles, cucurbituril capping, and montmorillonite exhibits dual functionality for simultaneous adsorption and degradation of organic dyes in wastewater. The easy recovery and catalytic function of the magnetic nanoparticles, along with the dual role of cucurbituril capping, contribute to efficient wastewater purification. The synergistic effect among the components in the nanocomposite enhances pollutant removal and catalytic activity, making it effective for wastewater treatment.

Summary: Membrane technology plays a vital role in various applications such as desalination, ultrafiltration, nanofiltration, reverse osmosis, and wastewater treatment. Janus membranes (JMs), with divergent hydrophilic/hydrophobic properties on both sides of their interface, are used in fluid flow to induce unidirectional fluid transportation. Two Janus type bi-layer polymeric membranes were successfully fabricated using a doctor blading method, with hydrophilic and hydrophobic surfaces on opposite sides.
