Popis:	The coprecipitate flotation of 137Cs from dilute aqueous solutions and simulated radioactive wastes using nickel hexacyanoferrate(II) as a coprecipitant and sodium lauryl sulfate, cetyltrimethylammonium bromide, or dodecyl amine as a collector was extensively investigated to establish the best conditions for cesium removal. Under the optimal conditions, removals exceeding 99% and decontamination factors higher than 110 could be achieved for the radioactive waste simulants. The results are compared with those obtained by conventional removal methods and are discussed in terms of the collector properties and the electrical state of the coprecipitate.
