| 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50mg／g，平衡吸附时间约为2h。

| 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; 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. |
