Impregnated resins prepared by the immobilization of an ionic liquid (IL, Cyphos IL-101, tetradecyl(trihexyl)phosphonium chloride) into a composite biopolymer matrix (made of gelatin and alginate) have been tested for re...

Textile dying processes that produce coloured effluents have a place among the less environmentally friendly industrial techniques. Chitosan is an aminopolysaccharide that has been widely studied for dye recovery. This b...

Metal cations can be adsorbed by chelation on amine groups of chitosan in near neutral solutions. In the case of metal anions, the sorption proceeds by electrostatic attraction on protonated amine groups in acidic soluti...

Uranyl ions can interact with amino-ligands and polymers such aschitin and chit(}san by compleX('l1ion and adsorption. Thb reaction can be ,tfteeted by certain circumstances, such ,L<; a direct exposure to visible light....

The modification of chitosan, by grafting of oxo-2-glutaric acid, allows its sorption performance to be increased. This enhancement of uptake ability is observed in overall sorption capacity and specificity in sorbing pa...
