Abstract: 

The comparison and assessment of the efficiency of using the precipitation of sparingly soluble metal hydroxides and fluorides for the extraction and pre-concentration of samarium isotopes from the solution simulating acidic leachate of the soil were made. It was shown that the precipitation of samarium isotopes was achieved quantitatively at the pH of about 7 and the co-precipitation of alkaline and alkaline earth elements did not exceed 20%. In contrast to that the fluoride precipitation was characterized by practically quantitative precipitation of alkaline, alkaline earth elements and Al, while the maximum extraction of samarium isotopes did not exceed 90%. The authors assumed that sequential precipitation procedures would be more effective for removing the bulk of the matrix without significant losses of samarium.
