In this study, the removal of a reactive (Remazol Yellow Gelb 3RS) and a basic (Basic Yellow 37) dye from aqueous solutions was investigated using cross-linked chitosan derivatives as sorbents (either powder or beads), which have been grafted with carboxyl and amide groups. The sorption behavior of the materials was examined through equilibrium, kinetic and pH-edges experiments. The reuse of sorbents was affirmed by sequential sorption-desorption cycles. Three isotherms (Langmuir, Freundlich… CONTINUE READING
