摘要
采用盐酸-硝硫(8∶2 V/V)湿法消解化探样品,再用碱溶液浸提,在硫酸-氯酸钾-二苯羟乙酸-二苯胍体系中采用催化极谱法快速同时测定钨、钼。改善了碱熔法效率低、空白高的缺点,该方法快速,简单,准确,适用于化探样品中钨钼元素的同时测定,并已应用于大批量化探样品的检测,取得良好的实际应用效果。
The geochemical exploration sample is melted with hydrochloric acid nitrate sulfur(8∶2 V/V) and extracted with alkali solution.In sulfuric acid-potassium chlorate-diphenyl glycollic acid-diphenyl guanidine system,tungsten and molybdenum are determined by catalytic polarography.This method is rapid,simple and accurate.It improves the low efficiency and high blank of alkali fusion method.This method applicables to the analysis for tungsten and molybdenum in geochemical exploration samples.It has been widely used in analysis of large quantities samples detection and obtained good effect.
