Taking clinoptilotite in Xinjiang as adsorbent, carried out the adsorption and desorption tests to the simulated radioactive waste water containing Cs + prepared by CsNO3, then discussed the isothermal absorption model and desorption dynamic behavior. The results show:clinoptilolite on removal rate of clinoptilolite to Cs+ reaches equilibrium after 16 h, the saturated dosage adsorption is at 196. 99 mg/g, the isothermal absorption model is Langmuir moel;; under the dosage of Clinoptilotite at 10 g/L, in order to insure the removal rate of Cs+ above 97% , the concentration of Cs+ in water must be less than 664. 55 mg/L; the desorption dynamic behavior of clinoptilotite to Cs+ is suit to the description of index model, and it will take 99 d to fully desorb the saturated adsorption Cs + in theoretically which proves the solid ability of clinoptilotite to Cs +%用CsNO3配制成模拟含铯放射性废水,以新疆某地产斜发沸石为吸附剂,进行了Cs+的吸附和解吸试验,并探讨了等温吸附模式及解吸动力学行为.结果表明:斜发沸石对Cs+的吸附在16 h时达到平衡,其饱和吸附量为196.99 mg/g,等温吸附模式为Langmuir模式；10 g/L斜发沸石用量下,要保证Cs+的去除率达到97％以上,水中Cs+浓度不宜超过664.55 mg/L;斜发沸石上Cs+的解吸动力学行为适合用指数模型描述,理论上,要使饱和吸附的Cs+完全解吸,耗时将长达约99d,显示出斜发沸石很强的固铯能力.
