摘要
文章介绍了一种测定钨精矿中钨的硫氰酸盐差示分光光度法,分析了标准样品及实际样品,结果与重量法一致。该方法准确、简单,可行性较强。
The method thiocyanate differential colorimetry that determines the content of tunsten in tungsten concentrates was introduced in the paper. We analyzed the reference material and samples and the results was in accordance with the results from cinchonine gravimetric method. The data had proved the method to be accurate, simple and good feasibility
