Abstract
Residual solutions contaminated with radioactive species require speci al treatment methods as the low concentrations of contaminants which m ay have important effects on the environment do not allow the direct u se of classical methods. The paper reports the results of studies to s eparate Ra-226(II) (0.73 Bq l(-1) concentration) by coprecipitation as Ba(Ra)SO4, followed by dissolved air flotation. The selection of the collector (by sigma and zeta determinations), optimum pH, concentratio n of the reactants, maturation time have been studied.
