Under hypoxic conditions,using the Beishan groundwater the influence of the CO2 concentration on the adsorption behavior of 99Tc in the Longdong clay was studied by batch method.Meanwhile,the buffering effect of clay rocks on the pH value of aqueous solution at different CO2 concentrations was discussed.The adsorption behavior of 99Tc on clay at different initial pH values was also researched.
