湿法磷酸中P_2O_5的快速测定

Rapid Measurement of P_2O_5 Content in Phosphoric Acid Solution

研究了用氢氧化钠两步滴定法测定湿法磷酸中P2O5含量的方法,测定结果与传统重量法、容量法吻合很好,方法简便快速,能充分满足湿法磷酸净化生产的控制分析要求。

The way of twi - titration by sodium hydroxide is used to measure the content of P2O5 in phosphoric acid solution. Compared with the traditional ways of capacity measurement and weigh measurement, it is not only exact, but rapider. It can be used in the industry.
