Abstract	Chemically modified chitosan incorporating amino quinoline was prepared by reacting 6-amino-2-chloroquinoline-3-carbaldehyde with chitosan; it was found to have high selective and chelating efficiency towards transition metal ions at pH 1–8. Enhanced adsorption capacity and strong affinity for Cu$^{2+}$ was observed as compared to Cd$^{2+}$, Ni$^{2+}$, and Co$^{2+}$ at 4–6 pH. This selectivity appeared to be independent of the size and the hardness of the ions. Potentiometric methods confirmed the order of selectivity which was independent of physical form of chitosan-amino-quinoline derivative (CAQ). CAQ was chemically synthesized and characterized by $^{1}$HNMR, $^{13}$CNMR, and FTIR techniques. $^{1}$HNMR results suggested a degree of substitution (DS) ranging from 14.6 to 95.2%. The adsorption capacity, ion selectivity of CAQ and antimicrobial activity against Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, and Candida albicans were investigated. Our results prompted us to further investigate the utility of CAQ as a green depolluting agent. The new chitosan-amino-quinoline derivative showed elevated potential as a good adsorbent, depolluting agent having selective memory for metal ions, and could be utilized especially for ion sequestration and solvent extraction.
