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(II) ions from aqueous solution. Crosslinked chitosan (1 g) was grafted with 29.96 × 10 M methyl methacrylate in the presence of 2.
