摘要
采用间歇法研究在不同环境条件下(浓度、固液比、温度、pH值、介质),新疆膨润土(简称XJ)对Sr2+、Cs+的吸附性能影响。结果表明:XJ对Sr2+、Cs+的吸附性能比较好,当Sr2+、Cs+浓度为0.01mol/L时,XJ对Sr2+、Cs+的吸附平衡时间约在7天左右,平衡吸附量分别为40mg/g、129mg/g。Sr2+、Cs+的浓度和不同固液比对XJ的吸附性能影响比较大,其次是不同介质、溶液的pH值和溶液的温度。
An intermittence method was adopted to study the adsorption of XJ bentonite （XJ for short） for Sr^2＋ and Cs^＋ under various conditions including different concentration, solid-to-liquid ratio ,temperature, pH value and groundwaters. The results show that adsorptive capacity of XJ for Sr^2＋ and Cs^＋ is high with adsorptive equilibrium time of 7 days and equilibrium adsorptive quantities were 40mg/g and 129mg/g when Sr^2＋ and Cs^＋ concentrations are 0.01mol/L. Adsorptive capacity firstly depends on the solution concentration and solid-to-liquid ratio, secondly on the groundwaters, pH value and temperature of the solution.
