【摘要】 本文研究了矿样分解后 ,利用Kel -F -TBP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的铂 ,通过方法的回收率试验 ,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】 The article is written after studying the decomposition of the sample ore, use Kel-F-TBP to separation and enrich platinum, it changes into cyaroplutinumacid and releases iodine when it reacts with potassium iodide after washing out and separation. Using I 2-CCl 4 extraction spectrophotometry to determine platinum in ore, through the experiment of rate reclamation, and in comparison with other methods, a rather satisfactory result has been got.更多还原
