摘要：
The adsorption capacity of the titled chelating resin for Pd(H) was about 1. 8 mmol/g-R on a dry basis. The rate of adsorption was high and adsorption equilibrium was attained within 15 minutes. The chelating resin showed a good adsorption ability for Pd(II) in the pH 0.5~4.5 region and the selective separation of Pd(I) from other di- and trivalent metal ions is possible by using HC1 solution. The Pt(IV) and Pd(I) loaded on the resin can be separated from each other by the elution with 1.0 mol/l NaOH, followed with 0.5 mol/l NaOH- 1.0 wt% KCN solution. The recovery of Pd(II) from sea water and prepared solution containing a large amount of several metal ions was carried out and the concentration ratio for Pd(II) by this resin was excellent. © 1990, The Chemical Society of Japan.
