| 摘 要： | 用铵盐改型钾丝光沸石，通过Ｘ－射线衍射，红外分析，分配系数，离子交换等温线及交换容量等的测定，就其结构及交换性能进行了研究；并与铵改型钠丝光沸石和天然斜发沸石等进行比较，表明ＮＨ４＾＋改型后的钾丝光沸石对Ｋ＾＋具有较高的交换容量和较好的Ｋ＾＋／Ｎａ＾＋分离效果。

| Abstract: | -type mordenite can be synthesized by ammonium advancing. The structure andcharacterization of ion-exchange of K-type mordenite were investigated by x-ray diffraction,infrared spectrum, ion-exchange isotherm line, the testing of distribution coefficient and capacityof exchange. It was found that K-type mordenite synthesized by ammonium advancing preferstoK+ compared with such as synthesized Na-type modemite by ammonium advancing, naturalclinoptilolite. |
