草酸银中银含量的快速滴定

Determination of the Content of Ag in Ag_2C_2O_4 by Precipitation Titration

利用沉淀滴定法测定银催化剂原料草酸银中的银含量,滴定的标准偏差小于1.0％。此方法简单快 捷,准确性和精密度高,能满足银催化剂生产过程中大批量草酸银中镊含量的快速分析。同时,考察了干扰离子对分 析精度的影响。

The silver content in silver oxalate as catalyst raw material was measured quantitatilely with precipitation titration method. The effects of the interferential ions on the analytical accuracy were examined. The results show that the relative standard deviation is less than 1%. The quick method is simple to use, and it can meet the damand of testing silver content in the process of mass production of silver catalyst.
