【摘要】 研究了矿样分解后利用巯基树脂富集铂 ,洗脱分离后转化为氰铂酸与碘化钾反应析出碘 ,采用I2 -CCl4 萃取光度法测定矿石中铂的方法。通过方法的回收率实验 ,并与其它测定方法进行比较 ,得到了较为满意的结果更多还原

【Abstract】 After decomposition of the sample ore, use mercaptoresin to enrich platinum, after washing out and separation,it changes into cyanoplatinum acid and releases iodine when it reacts with potassium iodide . Using I 2-CCl 4 extraction spectrophotometry to determine platinum in ore.Through the experiment of rate reclamation and comparison with other methods, a rather satisfactory result has been got.更多还原
