摘　　要：应用能量色散X射线荧光光谱法(EDXRF)对铂钌合金(铂含量为90%～96%)中铂含量进行测定。利用一套铂钌为主量的工作标样,测量并收集此工作标样所含元素的特征X射线光谱,建立标准工作曲线,编制和优化分析程序,测定铂钌合金中铂元素的含量。对铂钌合金样品的测试结果与其他方法进行比较,证明方法可行。铂钌合金中铂含量在90%-96%时,分析精度优于0.3%。The paper introduces determination of platinum content （90%-96%） in platinum ruthenium alloy by energy dispersion X-ray fluorescence spectrum method（EDXRF）.We use a set of work standard samples to measure and collect the characteristic X-ray spectrum of containing elements. Through establishing standard working curve, compiling and optimizing analysis program, the platinum content in platinum ruthenium alloy is determined. Comparison of the EDXRF results with that of other methods shows that the EDXRF method is a simple, rapid and fairly good method for measuring platinum ruthenium alloy. While the platinum contents in platinum ruthenium alloy were in the range of 90% to 96%, the analytical precision is better 0.30%.
