The synthesis of poly( N,N-dimethylacrylamide-co-acrylic acid) under different feed molar ratios was carried out by radical polymerization. Both homopolymers were also synthesized to compare the metal ion binding abilities. All polymers were water-soluble and were characterized by FTIR, 1 H-NMR, 13

We synthesized chitosan-based sorhents for the uptake of metal cations in acidic solutions. Chitosan was reacted with 8-formylbenzene sodium sulfonate and 4-formyl-1,3-henzene sodium disulfonate in the presence of NaCNBH3 to yield N-henzyl mono-and disulfonate derivatives of chitosan. IR and NMR spe
