摘　　要：通过实验研究了以盐硝混酸分解试样、氯化亚锡为还原剂、硫氰酸钠为显色剂,在酸性条件下通过测其吸光度测定高钼合金钢中钼质量分数的方法。该方法可缩短高钼合金钢中钼质量分数的测定分析周期,提高测量的准确度,操作简便,具有较好的实用性。The method to determine the molybdenum in high molybdenum alloy steel is studied by experiment. In the method, the specimen is dissolved in a mixed acid of hydrochloric acid and nitric acid, using the SnCl2 as reducing agent, the NaSCN as chromogenic reagent, the content of molybdenum is determined by measuring the absorbance in acidic conditions. The method can not only shorten the analysis cycle, improve the accuracy, but also is easy and simple to handle. So it has better practicability.
