Special Issue Information

Dear Colleagues,

The pollution of air, water, and soil is a result of industrial growth and rapid population growth. The uncontrolled discharge of various pollutants from homes and agricultural and industrial sources into lakes, rivers, seas, and groundwater can have detrimental effects on ecotoxicological conditions and pose a health concern. Pollutants including detergents, pesticides, dyes, drug residues, chromates, phosphates, heavy metals, phenols, and so on are not effectively removed with conventional wastewater treatments (i.e., membrane filtering, advanced oxidation process, biodegradation, etc.).

Therefore, numerous investigations have brought into focus adsorption for the removal of pollutants from water. The main advantages of adsorption are its low cost, simplicity, selectivity, fast removal, and high efficiency of removal of pollutants even from diluted aqueous solutions.

This Special Issue is devoted to new research and recent contributions on the various adsorbents and materials based on natural materials (in unmodified form or after modification or functionalization), composites, functional materials, waste of industry and agriculture (sawdust, citrus peels, nut shells, eggshells, fruit seeds, bones, coffee grounds, textile waste, etc.), green adsorbents, and nanomaterials in water and wastewater treatment via the principles of sustainable development. For this Special Issue, relevant topics include (but are not limited to) the following: case studies, the kinetics of adsorption, regeneration and recovery assessments, process design and mechanism analysis of removal using theoretical calculation methods, modeling, and simulation.

We would like to invite you to contribute original research and review papers on water/wastewater treatment and purification techniques and materials. We look forward to receiving your contributions.

In an attempt to reuse fibrous textile waste and, at the same time, to address dye pollution in textile wastewater, waste cotton-based yarn was utilized as a cheap and sustainable adsorbent, as well as a row material for carbon adsorbent production. Unmodified yarn and cotton-based carbon adsorbents were used as adsorbents for dye removal from water. Cotton and cotton/polyester yarn samples underwent thermal modification through carbonization followed by chemical activation with KOH. Various techniques, including scanning electron microscopy, Fourier transform infrared spectroscopy, nitrogen adsorption–desorption isotherms, and surface charge determination, were employed to analyze the morphological and surface characteristics of the cotton-based adsorbents. Adsorption properties were evaluated by testing the removal of selected cationic and anionic dyes from water. The impact of temperature, initial pH and concentration of the dye solution, and contact time on adsorption were investigated, and experimentally obtained data were analyzed using theoretical models. While carbonization alone did not significantly enhance adsorption properties, activated samples exhibited high efficacy in removing both cationic and anionic dyes from water. Despite the negative influence of the polyester component in the carbon precursor on the efficiency of activated samples in removing methyl orange, the results indicated that activated cotton and cotton/polyester yarn could be used to prepare highly efficient adsorbents for the rapid removal of methylene blue from real wastewater samples.
