钢材中锑磷钼蓝光度法测定磷量的方法研究

Study on the determination of phosphorus content methods of antimony phosphomolybdate blue photometric method in steel

该文介绍了用锑磷钼蓝光度法测定钢铁及合金中的磷量的方法。对于钢材及合金中磷元素的分析,在排除了硅、铬、砷等元素的干扰后,以锑磷钼蓝光度法进行显色反应,不仅回收率高,而且准确度、精密度高,方法简单快捷。

This paper introduced the antimony phosphomolybdenum blue photometric method for the determination of phosphorus content in iron steel and alloy method.For steel and alloy element P in the analysis,the removal of silicon,chromium,arsenic and other elements after disturbance,antimony phosphomolybdenum blue photometric method for the color reaction,not only the recovery rate is high,and the accuracy,high precision,simple and convenient method.
