【 摘 要 】

This report discusses the experimental program conducted at ANL to study the performance of in-situ-formed magnetite for the removal of Sr, Pu, Np, U, Am, and Cs from the Savannah River Site (SRS) tank waste. The boundaries for the experimental work were defined based on the operational envelope developed earlier in collaboration with SRS. In situ formed 'magnetite' is actually a mixture of Fe(II) and Fe(III) oxides and hydroxides, including magnetite. Decontamination factor (DF) values were measured for both magnetite and monosodium titanate (MST). Magnetite DF values were found to be superior to MST for all isotopes studied.
