摘　　要：在硫氰酸盐全差示光度法测定高含量钼方法的基础上，对分析结果的误差进行了系统研究，以标准物质校准提高准确度，建立了高精度测定三氧化钼中钼的新方法，ＲＳＤ０．０５４％，线性范围宽，钼在０～６ｍｇ·１００ｍＬ－１符合比耳定律，直读浓度，用于高纯三氧化钼中钼的测定结果满意。On the basis of determinating high content with sulphate photometic method,the error for the analytical results is studied.A new method of determination for molybdenum in molytrioxide with high accuracy is raised.RSD is 0.054%,and the linear range is wide,the molybdenum is obeyed the Bill law at 0～6 mg·100mL -1 .There is a satisfied result by using direct reading concentration method in high pure molytrioxide.
