[en] Sorption of fission products of radionuclides ¹³⁷Cs, ^89,90Sr, ^90,91Y, ⁸⁶Rb, ¹³³Ba, ⁹⁵Zr+⁹⁵Nb, ⁹⁵Nb, ^103,106Ru, ^141,144Ce, ^115mCd, ¹¹³Sn, ¹²⁵Sb by hydroxides Fe(III), Mn(IV) on the background of 1 mol/l of NaNO₃ at the pretense of ions SO₄^2-, C₂O₄^2- at a wide ph range (1+14) is studied in present work. Optimal conditions of extraction of each radionuclide by sorption on inorganic sorbents are defined.
