Studies on Hg(II) ion retention properties of cross-linked graft copolymer of acrylic acid and its analytical application

摘要

The effects of different parameters such as time, concentration, pH and temperature, on metal ion retention properties of the polymer have been investigated. Metal ion adsorption kinetics, isotherms and thermodynamics have been studied. A plausible mechanism for mercury ion retention has been suggested. Mercuric ion has been isolated quantitatively from various synthetic mixture containing metal ions (Ni~(2+), Cd~(2+), Pb~(2+) and Zn~(2+)).
