摘　　要：硫氰酸盐差示光度法测定高含量钼铁合金在测定同时含高含量钼和钒的合金钢时,有显色不稳定及钒显色干扰测定的问题。结合实际情况,针对此合金产品:钼钒铝(40:40:20)中钼含量的检测,利用基体匹配方式,采用差示光度法对该产品中的钼含量进行测定,得到了理想的结果。The determination of high content ferromolybdenum alloy by thiocyanate differential spectrophotometry has the problems of unstable color development and vanadium color development interference in the determination of alloy steel containing both high content molybdenum and vanadium.According to the actual situation,for the detection of molybdenum content in this alloy product:molybdenum vanadium aluminum (40:40:20),the matrix matching method was used to determine the molybdenum content in this product by differential spectrophotometry,and the ideal results were obtained.
