抄録

An experimental investigation of the adsorption properties of metal ions onto gel was carried out by using hydrolyzed polyacrylamide gel and copper sulphate, ferrous ammonium sulphate and ferrous sulphate solutions. Considering that carboxyl groups in the gel bond with the metal ions according to their electric charge number, the adsorption properties were examined on the basis of dissociation equilibriums from monocarboxyl to dicarboxyl acid. From theoretical analyses, empirical equations that give the amount of metal ions adsorbed on the gel were obtained. For the adsorption equilibrium of copper and ferrous ions, the amount of ions adsorbed within the gel can be calculated well from the initial and equilibrium concentrations of the metal ions in aqueous phase, the concentrations of hydrogen ions, the weight of the gel and the volume of solution used.
