摘要
晶体的溶解与晶体的生长存在着密切的联系,详细研究沸石晶体的溶解行为将有助于更好的理解沸石晶体的生长机理。鉴于目前对沸石晶体的碱处理溶解行为的研究尚处于初始阶段,所以从沸石碱溶解的几点关键内容出发,如沸石的硅铝比对沸石碱处理的影响,焙烧"活化"后沸石的碱处理溶解行为的变化,沸石与其无定形前驱物的溶解性差异以及沸石的溶解机理和溶解动力学方程方面,综述了有关沸石碱处理溶解研究方面的最新动态。
Because the dissolution of crystals is closely related to the growth process of them, carefully studying the dissolution behavior of zeolites will do help for the better understanding of the growth mechanism of zeolites. In this paper the advances achieved in the alkali dissolution of zeolites which focus on such key points as the influence of the Si/Al ratios of zeolites on the dissolution process of them, the dissolution behavior of 'activated' (calcined) zeolites, the difference in the dissolution behavior between zeolites and their precursors as well as dissolution mechanism and dynamic equations of zeolites are reviewed.
