摘要: 斜发沸石与可溶性磷酸盐溶液进行交换反应时,伴随着沸石与溶液间的阳离子交换,也发生了沸石对磷的吸附作用;沸石对磷的吸附作用除与沸石中所含的可交换Ca2+相关外,可能还与沸石阴离子骨架中Al对磷酸根的弱的键合作用相关;沸石所吸附的磷可被某些溶液解吸下来。斜发沸石的阳离子交换性能及对磷的吸附和可解吸性能,在土壤改良中起到类似营养元素储存库的功能,因而,在农业生产中具有重要的应用价值。

关键词: 斜发沸石, 磷, 吸附, 解吸

Abstract: When an exchange reaction takes place between clinoptilolite and solube phosphate solutions,companied with cation exchange between the zeolite and solution,it occurred also for the zeolite to adsorb phosphoric ions.Adsorption of the zeolites to phosphoric ions may be related to a weak bonding action of Al in the zeolitic anionic framework with phosphoric ions,besides that it is related to exchangeable Ca2+ of the zeolites.Phosphoric ions adsorbed by the zeolites can be eluted with some solutions.Cation exchange propeties of clinoptilolite and its adsorption and desorption to phosphoric ions have a function of storage for nutritive elements in soil improvement,so that the zeolite has important useful values in agricultural production.

Key words: Clinoptilolite, Phosphoricions, Adsorption, Desorption
