The use of membranes prepared with alginate and chitosan to adsorb paraquat aqueous solution was evaluated as a potential alternative technique for remediation of contaminated water. Production of bilayer membranes was ...

This study investigated the adsorption behavior of the herbicides diquat, difenzoquat and clomazone on biopolymer membranes prepared with alginate and chitosan (pristine and multi-layer model) for contaminated water ...

The contamination of the environment by potentially toxic metals is highlighted by possible impacts of their high availability. Thus, the development of alternative absorbents that can be used in the remediation of ...

The adsorption capacity of copper, zinc, cadmium and lead by Asterococcus superbus, a freshwater microalgae, was studied in batch mode. The Langmuir, Freundlich, Temkin and Dubinin?Radushkevich models were applied and ...

Enormous amounts of pesticides are manufactured and used worldwide, some of which reach soils and aquatic systems. Glyphosate is a non-selective herbicide that is effective against all types of weeds and has been used for ...

Cellulose-based materials are the most widely used green materials because of their abundance, sustainability, biodegradability, and functionalizability. The capability of cellulosic materials as adsorbents and coagulants ...
