摘要
用四种N_(235)萃淋树脂研究铂的吸萃性能结果表明:①当盐酸浓度1～8N树脂都能有效地吸萃铂,其吸萃率均>99%,但ER型N_(235)树脂略优于CL型。②此法可用于铂精炼母液和废铂催化剂HCl+Cl_2溶解液中回收铂。
The adsorption-extraction properties of platinum with four N_(235) extration-elution resins were studied. It was shown from the results that: (1) the four resins were effective for adsorption-extraction of platinum at[HCl] be 1～8M, the extraction rates were above 99.0%, The extraction properties of ER-N_(235) resins were better than CL-N_(235). (2)This method can be used to recover platinum from the liquors of platinum-refining and the solution . of dissolving the spent Pt catalysts with HC1 and Cl_2.
