Abstract
Sorption and migration experiments were performed by both batch and column methods, to study influence of humic acid complexing on the mobility of {sup 60}Co, {sup 85}Sr and {sup 137}Cs in a coastal sandy soil. The study focuses on a correlation between molecular-weight of dissolved humic acid and ability of the complexing with the radionuclides in liquid phase. Dissolved humic acid was complexed with {sup 60}Co and {sup 85}Sr. The interaction ability of {sup 60}Co was independent of molecular-weight of humic acid, while that of {sup 85}Sr depended on. The mobility of {sup 60}Co increased under the condition with coexistence of humic acid as well as its sorption ratio decreased. The distribution profile of molecular-weight of {sup 60}Co was kept at a constant in the solution before and after the sorption experiment, due to completing the sorption and complexation equilibrium. The mobility of {sup 85}Sr increased under the condition with coexistence of humic acid, in spite of the sorption ratio of {sup 85}Sr was not affected by the coexistence. Such contradiction was caused by different kinetics between the batch and column methods. The sorption ability and mobility of {sup 137}Cs were not affected by the coexistence of the humic acid.
