摘要
研究了矿样分解后利用巯基树脂富集锰,洗脱分离后转化为高锰酸钾与溴化钾反应析出溴单质,采Br2-CCl4萃取光度法测定矿石中锰的方法。并对样品溶解方法、共存元素及其影响、内标元素的选择等进行了研究,建立的分析方法简便快速,精密度和准确度较好。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 is written after studying the decomposition of the sample ore,use the application of sulfhydrly compounds to separation and enrich manganese ,it changes into KMnO_4 and releases Br_2 when it reacts with KBr after washing out and separation. The factors such as the preparation of the sample solutions, the interference of matrix and co-exiting elements, these lection of the internal standard element have been investigated. The established method is convenient, rapid and of good precision.Using ex...
