摘　　要：利用硫氰酸盐光度法测定钨，通过加入不同掩蔽剂优化试验条件排除了钨矿浸出液中不同杂质的干扰，使得此方法在检测钨矿浸出液中钨的质量浓度更加简便、准确、可靠，方法加标回收率达98．2％～102．8％，RSD〈4．0％，与样品实际值的相对误差≤2．0％。The determination of the tungsten in the tungsten ore leaching solution is researched with the method of thiocyanate spectrophotometry. By optimizing test conditions and adding different masking agent exclude the interference of different impurities in tungsten ore leaching solution. The accurate results can be acquired rapidly and easily as well as reliably. The adding standard recovery rate of the method is 98.2%-102.8%, RSD〈4.0%, relative error to the actual value of the sample is≤2.0%.
