Abstract

1407257 Extracting uranyl nitrate BAYER AG 18 Dec 1972 [18 Dec 1971] 58277/72 Heading CIA [Also in Division C3] Salts such as uranyl nitrate may be extracted from aqueous solutions containing them, by passing the solution through a column which contains a porous polymer containing pores of molecular dimensions, and which is a polymer of a polyvinyl compound and optionally a monovinyl or monovinylidene compound, which polymer also contains an extractant which is an organic solvent. In the exemplification the polymer is a styrene-divinylbenzene copolymer and the extractant is tri-n-butyl phosphate.
