| 摘 要： | 本文研究了用电位滴定法测定模拟高放废液中游离酸的方法。用草酸钾做络合剂以消除Ｆｅ＾３＋、Ａｌ＾３＋、Ｎｄ＾３＋等多种水解离子的影响，用标准碱直接进行电位滴定，即可快速准确地测定模拟高放废液中游离酸的含量。方法的相对标准偏差为１．８％，标准加入回收率为１００－１０１％，能为放射性废物固化试验提供可靠的分析数据。 |

| Abstract: | A potentiomtric titration method for the determinatio for the determination of free acid in simulated high level liquid wste is ddscribed. The test sample is directly titrated under the mask of hydrolizable ions, such as Fe3+, Al3+ and Nd3+, with 8% potassium oxalate. The relative standard deviation of analysis is 1.8% and the recovery is 100-101%. This method is simple,rapid and accurate, and can be used to provide analytical data for the solidification resarch or radioactive waste. |
| Keywords: | Potentiometric titration simulated high level liquid waste free acid |
