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.
