摘要 研究以天然沸石为基体制备无机离子交换剂的方法;利用离子交换剂的吸附等温曲线,可得到阳离子最大的交换容量;通过离子交换剂的吸附动力学曲线,可求得吸附平衡时间。结果表明,以改性剂M为改性材料,在天然沸石与改性剂M质量比为4∶1时制得的无机离子交换剂的阳离子交换容量最高,常温时能达50 mg/g,平衡吸附时间约为2 h。

Abstract： Inorganic ion exchangers were produced from natural zeolite and its adsorption isotherm curve was protracted and its cation exchange capacity was also measured.Adsorption kinetic curves of NH~+_4 on Mesolit were employed to obtain the equilibrium adsorption time.The results showed inorganic ion exchanger had the highest cation exchange capacity of 50 mg/g at normal temperature when Improver A was used as modified material and natural zeolite and Improver A were mixed with a ratio of 4∶1,the equilibrium adsorption time was 2 h.
