| 摘 要： | 采用磷钼酸铵容量法测定磷化液中磷(以磷酸二氢锌计)的含量,通过在基础溶液中加入磷标准溶液,与不加入任何干扰物质的磷标准溶液作对比试验,验证分析方法的可靠性。实验结果得出:通过F、t检验法,分析方法的准确度和精密度都较好;回收率在99.0%～100.0%之间,达到分析要求。

| Abstract: | A volumetric method of ammonium phosphomolybdate for the determination of phosphorus content(counted with zinc dihydrogen phosphate) in phosphated solution was reported in this paper.The reliability of this method was proved by comparing the standard phosphorus solution added into the basic solution with the noninterference standard phosphorus solution.The results show that this analytical method has a good accuracy and precision detected by F and t methods.The recovery ratio is 99.0% ～ 100.0%,and meets the requirements for analysis. |
