New efficient chitosan derivative for cu(ii) ions removal: characterization and adsorption performance
A new crosslinked chitosan grafted with methyl methacrylate (M-CTS) adsorbent was synthesized via free radical polymerization for effective removal of Cu(Q) ions from aqueous solution. Crosslinked chitosan (1 g) was grafted with 29.96 x 10(-1) M methyl methacrylate in the presence of 2.63 x 10(-1) M...
