| 内容記述 | Natural zeolite, clinoptilolite, produced in Akitra prefecture has a large potential for various practical usage. In this paper, we have tried to synthesize cation exchangers and geopolymers from the zeolite using sodium-silicate and sodium hydroxide as activator. We have varied some parameters like alkali concentration, particle size and curing time in order to improve the quality of cation exchanger and geopolymeric product. The NH₄⁺ retention capacity of the clinoptilolite is enhanced either by increasing alkaline metal cations content with chemical modification or by reducing particle size or increasing specific surface with mechanical modification. The geopolymer materials synthesized through mechanochemically treated clinoptilolite using NaOH and sodium silicate solutions showed increasing crushing strength up to around 25 MPa with increasing curing time. | |||||||||
