The type of cation and their exchange degree are the important factors that influence the adsorption performance of zeolite adsorbents.

沸石分子筛吸附剂中阳离子的类型和离子交换度是影响其吸附性能的重要因素。

CONCLUSION the adsorption should be tested when automatic sampling device is used to determine dissolution and releasing degree for different drugs, or the results of determination might be affected.

结论药品测定溶出度或释放度时，应先考察溶出度测定仪的自动取样装置对其是否有吸附作用，否则影响测定结果。

WAXD results indicate metal ions adsorbed onto both the amorphous and crystal regions of AECTS, and the destructive degree of the crystal region was in direct proportion to the adsorption capacity.

WAXD分析显示，金属离子的吸附不仅发生在非晶区，也渗透到晶区，对晶区的破坏程度正比于吸附量。
