摘要
研究了矿样分解后利用咪唑啉纤维树脂分离富集铂,洗脱分离后转化为氰铂酸与碘化钾反应析出碘,采用I2-CC l4萃取光度法测矿石中铂的方法。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。
The article studies the decomposition of the sample ore by applying the Imidazoline Fiber to enrich platinum, then it changes into cyaroplutinumacid and releases iodine when it reacts with potassium after washing out and separation. Using I2 - CCl4 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 achieved.
