Preparation Of Chitosan Derivatives By Polyethyleneimine Modification For The Removal Of Acid Red 88 Dye

This research is aimed to propose an alternative method to synthesize an inexpensive, green and effective adsorbent for the removal of Acid Red 88 (AR88) from aqueous solution. Chitosan (Cs) was successfully modified with polyethyleneimine (PEI) through a cross-linker either calcium chloride (CaCl2)...
