Adsorption isotherms for single metal ions(Ca<SUP>2+</SUP>, Fe<SUP>3+</SUP>, Cu<SUP>2+</SUP>, Zn<SUP>2+</SUP>, Cd<SUP>2+</SUP>, or Pb<SUP>2+</SUP>) in acidic solutions at 25 °C on 9 types of commercial chelating resins were obtained. The results could all be expressed by the isotherm equation, <I>Q</I>=<I>Q</I><SUB>max</SUB>⁄(1+<I>AC</I><SUB>M</SUB><SUP>−α</SUP><I>C</I><SUB>H</SUB><SUP>β</SUP>), reported in the preceding paper. The parameters α and β, which indicate respectively the influences of concentrations of metal ion (<I>C</I><SUB>M</SUB>) and hydrogen ion (<I>C</I><SUB>H</SUB>) on the adsorption capacities (<I>Q</I>), were discussed in relation to the properties of the chelating resins and the metal ions.
