摘要
采用静态吸附实验方法,研究了吸附时间、溶液p H值、吸附剂加入量和溶液初始浓度等因素下,新疆沸石、缙云沸石及赤峰沸石对Cs+吸附性能,结果表明:在处理较低浓度的含Cs+废液时,新疆沸石和缙云沸石对放射性核素Cs+的吸附性能差别不大,并且两者的吸附性能明显优于赤峰沸石对Cs+吸附效果;在处理较高浓度的含Cs+废液时,新疆沸石对放射性核素Cs+吸附性能最优于缙云沸石,而赤峰沸石对Cs+的处理效果最差。因此,新疆沸石较适宜处理不同浓度的含Cs+放射性废水,该研究结果可为放射性废水处理、高放废物地质处置库中的人工屏障设计及集成缓冲材料开发提供科学依据。
The static adsorption experiments were carried out to investigate the adsorption performance of strontium on zeolite from different mining area under the condition of different adsorption time, pH values, adsorbent dosage and initial concentration. These results indicated that the adsorption performance of Xingjiang zeolite for Cs ^＋ was just as better as Jinyun zeolite, and the adsorption performance of Chifeng zeolite for Cs ^＋ was poorer than others under low concentration caesium -containing waste water. However,the adsorption performance of Xingjiang zeolite for Cs ^＋ was best, and Jinyun zeolite was better than Chifeng zeolite under high concentration caesium - containing waste water. Therefore, Xinjiang zeolite was suited to treat different concentration caesium - containing waste water, and the research results would provide scientific basis for treating radioactive waste water and designing integrated buffer material of disposal repository for high - level radioactive waste（HLW） in our country.
