摘要
采用铍盐共沉淀—钼蓝分光光度法对钒氮合金中微量磷进行测定。通过回收试验、精密度试验、准确性试验多方证明了该方法具有良好的精度和准确度,完全满足目前钒氮合金生产中磷的分析要求,已成功地应用于钒氮合金中磷含量的测定。
Trace phosphorus in V-N alloy was determined by beryllium salt coprecipitation—molybdenumblue spectrophotometry. This method was proved to have good precision and veracity. The low limit of determination is 0.001 6%, which completely satisfy the analytical request. The method is successfully applied to the determination of phosphorus in V-N alloy and the determining results are satisfying.
