水杨基萤光酮—溴化十六烷基三甲铵三元络合物分光光度法测定钢铁及地质样品中W(ε=1.3×10~5 l·Mol~(-1)·cm~(-1))和Mo(ε=1.4×10~5 l·Mol~(-1)·cm~(-1)),是目前光度法测定微量W和Mo的高灵敏度方法之一。本试验是应用此法在一份溶液中同时测定化探分散流样品中的微量W和Mo。方法灵敏度较高,重现性较好,不必考虑W、Mo的相互干扰问题。在W、Mo含量相差不悬殊的情况下(10倍量以内),可获得满意结果。该法适宜于化探分散流样品中1～XXX ppm W和Mo的分析。
Determination of W (ε = 1.3 × 10-5 mol · cm -1) in Steels and Geological Samples by Salicylfluorone-Cetyltrimethylammonium Bromide Ternary Complex Spectrophotometry ) And Mo (ε = 1.4 × 10-5 mol · cm -1) are one of the most sensitive methods for the determination of trace W and Mo by spectrophotometry. This test is the application of this method in a solution of simultaneous determination of geochemical dispersed trace flow trace W and Mo. The method has high sensitivity and good reproducibility, so it is unnecessary to consider the mutual interference of W and Mo. In W, Mo content is not disparities between the case (less than 10 times), to obtain satisfactory results. The method is suitable for the analysis of 1 ~ XXX ppm W and Mo in the geochemical dispersion flow sample.
