中文摘要：
通过静态吸附实验，研究了水相pH值、239Pu初始浓度、离子种类等因素对239Pu在高庙子膨润土中吸附行为的影响。吸附试验表明，239Pu在高庙子膨润土样品中的吸附平衡时间约为24h，且其吸附分配比凰值随pH值而增大，随239Pu的初始浓度增大而减小；而对于不同离子种类对239Pu在膨润土中的吸附：阴离子中CO3^2-对膨润土的吸附影响最大，吸附分配比Kd值最小，其次为HCO3^-和SO4^2-，而Cl^-和NO3^-对膨润土的吸附基本没有影响。
英文摘要：
Adsorption behavior of 239pu by Gaomiaozi bentonite as a function of the factors of aqueous phase pH value, 239pu initial concentration and ionic species is studied by static adsorption experiments in this paper. The following results are obtained. Adsorption equilibrium time of 239pu by Gaomiaozi bentonite samples is about 24 h, and the adsorption distribution ratio Kd value of 239pu increases with the pH value, but decreases with increasing initial concentration of 239pu. And adsorption of 239pu by bentonite samples with different ionic species show that anions affect the most on adsorption of bentonite is CO32-, followed by HCO3-and SO42-, whereas Cl- and NO3- hardly have any influence on the adsorption of bentonite.
