摘要
采用静态吸附实验方法,研究吸附时间、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Sr2+吸附性能,结果表明:同一吸附条件下,3种沸石对放射性核素Sr2+的吸附性能由大到小依次为:新疆沸石>赤峰沸石>缙云沸石,并且新疆沸石适宜处理低浓度的含Sr2+放射性废水,该研究结果可为放射性废物处理、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了科学依据。
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 Sr2＋was best, and Chifeng zeolite was better than Jinyun zeolite under the same adsorption conditions.Therefore, Xinjiang zeolite was suited to treat low concentration strontium-containing wastewater, 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.
