浸出试验是测定放射性废物固化体性能的主要手段之一.IAEA于1969年推荐了一个标准浸出试验方法,其中对浸出实验的有关方面都做了规定.不少从事浸出试验的工作者都参考这个方法,同时又根据各自的情况进行了必要的修改.由于IAEA推荐方法本身就存在一些缺陷,再加之不同的修改,致使各工作者测定结果的相比性减弱了,有些甚至无法相比较.ISO于1982年发布了ISO6961,此国际标准也有一些不妥之处.为制定我国的标准浸出试验方法,有必要对浸出试验的细节进行试验研究和验证.影响浸出试验准确度的因素很多,因篇幅所限,本文只能对部分问题进行探讨.
Leaching test is one of the main means to determine the performance of solid waste radioactive waste IAEA in 1969 recommended a standard leaching test methods, which are related to the aspects of the leaching test are made.Many workers engaged in the leaching test refer to this Method, at the same time, make the necessary changes according to their own situation.As the IAEA recommended method itself has some flaws, combined with different modifications, resulting in the comparison of the results of the various workers weakened, and some even can not be compared.ISO Released in 1982 ISO6961, this international standard also has some inappropriate .In order to develop China’s standard leaching test method, it is necessary to test the details of the leaching test and verify that the impact of leaching test accuracy of many factors, due to space Limited, this article can only explore some of the issues.
