摘要：
Purolite S110 has been used for removal of M(II) complexes with Dissolvine GL-38 (GLDA). The sorption efficiency of Purolite S110 with respect to the Zn(II), Pb(II) and Cd(II) complexes with GLDA depends on contact time, concentration and accompanying ions. Average sorption efficiency (S%) is as follows: 64% for Zn(II), 62% for Cd(II) and 97% for Pb(II) complexes with GLDA. The kinetic data are well described by the pseudo-second-order rate equation. To describe the sorption process, the Langmuir and Freundlich adsorption equations were applied. The interactions of M(II) ions with Purolite S110 was confirmed by the attenuated total reflection (ATR) FT-IR.
