摘　　要：膨润土阳离子交换容量是判断膨润土的主要依据,国标给定方法在实验测试中出现结果偏差大、不稳定的现象,本法对系列统一加入氯化钡,使测定结果更加稳定,偏差变小。The cation exchange capacity of bentonite is the main basis for judging bentonite. The results of the national standard given method have large deviation and unstable phenomenon in the experimental test. The unified addition of barium chloride in this method makes the determination results more stable and the deviation smaller.

关 键 词：钙基膨润土 阳离子交换量 氯化钡
