FIELD: chemistry.
SUBSTANCE: invention relates to methods of extracting cerium (IV) by electroflotation from waste water, depleted or industrial raw material. Described is a method of extracting cerium (IV) from an aqueous solution, including electrofloatation with insoluble anodes, in which treated water is mixed with a cationic flocculant based on highly polymerised polyacrylamide with weight ratio of cerium (IV) ions to flocculant [1]:[0.008–0.1], wherein electrofloatation is performed at current density of 0.4 A/l for 10 minutes.
EFFECT: technical result is wider of range of initial concentrations of cerium (IV) ions while maintaining high degree of extracting cerium (IV) ions.
