摘　　要：本文通过实验研究了人工合成ＮａＡ型沸石及天然沸石矿物对锶铯的吸附作用。研究表明人工合成ＮａＡ型沸石对锶铯的吸附性能优于天然沸石、且迁移率低，是吸附中低放核素９０Ｓｒ及１３７Sorption of 90 Sr, 137 Cs on the NaA zeolite is studied experimentaly in this paper.The results show that sorption properties of strontium and cesium on the NaA zeolite are superior to the natural zeolite, and the migrating rate of Sr,Cs is low.It is suggested that the NaA Zeolite is well suited for the sorption of strontium and cesium.
