WebThe CL Resin has high selectivity for Pd(II) and Ag(I), whereas the D W values of the other tested metal ions are low. D W values for Ag(I) remain high over a wide pH range (from 1M H 2 SO 4 to dilute sulfuric acid, pH 5). Ag(I) is therefore extracted and remains fixed on the resin over a wide range of pH values. http://www.dardel.info/IX/other_info/selectivity_c.html
