"Evolution of actinide partitioning to colloids upon subsurface migration in the vicinity of Karachay Lake (PA ''Mayak'', Russia) was studied by micro- and ultrafiltration and sequential extraction. Colloidal matter was characterized by SEM-EDX, TEM and photon-correlation spectroscopy," scientists in Russia report.
"Samples were collected from wells with different redox conditions i.e. from higly oxic to rather reducing. Under oxidizing conditions uranium and neptunium is readily washed out from colloids. Plutonium and americium are present in colloidal matter mainly as hard-soluble species. Under oxidizing conditions plutonium and americium are predominantly ...
