【摘要】 通过ＸＲＤ和吡啶吸附的ＩＲ技术考察了水合１３Ｘ沸石与碱金属盐类间的固相离子交换反应，结果表明，此类固相离子交换在室温下即可发生。一次交换的程度有限，通过重复交换可提高交换度，体积较大的Ｃｓ＋比Ｋ＋难于交换，高温焙烧有利于提高Ｃｓ＋的交换度。更多还原

【Abstract】 The solid-state ion exchange between hydrated 13X zealite and alkaline metal salt was studied.XRD patterns and IR spectra of the exchanged samples show that the exchange reaction can occur at ambient temperature. The exchange extent can be enhanced by repeated exchange.Compared with K+ ion, the bulky Cs+ ion is more difficult to replace Na+ ion.The calcination at a higher temperature is favourable to increasing the exchange degree of Cs+-exchanged sample.更多还原
