Effective diffusivity was determined for Np(IV) in bentonite material in presence of carbonate and for Pu(IV) in presence of fulvic acid. Adsorption of actinides onto negatively charged mineral surfaces were investigated under conditions that actinides were predominantly present as anionic complex species. The results of this study will reveal behavior of actinides under various geological environments.
