Extraction process in Sm3+ aqueous solutions from nitrate media by sodium dodecylsulfate as collector is investigated. Distribution coefficients on depending of the pH aqueous phase in different concentration of Sm3+ is obtained.
The ion flotation of cerium (3+) and samarium (3+) from nitrate solutions by use of sodium dodecyl sulphate as a collector with addition of sodium chloride has been stated. The ratio of distribution coefficients and separation coefficient as function of the pH-aqueous phase with different concentration of chloride-ions has been analyzed. The separation coefficient has rise from 1,3 till 4,75 when chloride has been added.
