The latest tendency of the scientific community regards the development of different classes of green materials able to solve pollution problems caused by industrial and human activity. In this paper, chitosan and diatomite ...

Textile activity results in effluents with a variety of dyes. Among the several processes for dye-uptaking from these wastewaters, sorption is one of the most effective methods, chitosan being a very promising ...

Carra sawdust pretrated with formaldehyde was used to adsorb RR239 (reactive azo dye) at varying pH and zerovalent iron (ZVI) dosage. Modeling of kinetic results shows that sorption process is best described by the ...

Hydrogels seem as possible materials to solve the dyes contamination in water. In this study, polyvinyl alcohol (PVA) based nanocomposite hydrogels having 3 wt.% bentonite were prepared by an innocuous physical crosslinking ...
