摘要：

The titled chelate resin showed a good adsorption ability for Ca2+, Ba2+ and Sr2+ in the pH 8.0-10.0. The adsorption capacity of the titled chelating resin for Ba2+ was about 1.6 mmol/g-R on a dry resin. The rate of adsorption was high and adsorption equilibrium was attained with in 15 minutes, Ba2+ and Ca2+ or Ba2+ and Sr2+ loaded on the resin can be separated from each other by the elution with 1.0 mol dm(-3) CH3COONH4-20 vol% acetone solution, followed with 1.0 mol . dm(-3) HCl,
