摘要：
Chitosan was modified with methylglycinediacetic acid (MGDA) and used as sorbent for removing heavy Cu(II), Zn(II), Pb(II) and Cd(II) metal ions from aq. wins. at ion:MGDA mole ratio 1:1. The sorption efficiency increased with increasing metal ion conc. and with decreasing pH. The sorption kinetics was described by the pseudo 2(nd) order mechanism.
