“…This work, initiated by decontamination problems arising out of the liquid metals fuel reactor program, is of borderline interest in analytical chemistry now but may well be of more direct use to analysts before too long. Rare earths have been extracted from molten bismuthuranium by contact with molten lithium and potassium chloride (14,15,51,124) and the distribution of plutonium between aluminum and bismuth (125) and between uranium and silver (203,208) has been studied. THEORY A helpful organizational pattern for the extraction process, based on three essential aspects common to every metal extraction process, has been proposed (148).…”
