| Popis: | Potassium nickel hexacyanoferrate(II) matrix was prepared and characterized. Purification of neutron- activation 99 Mo-molybdate(VI) solutes from some residual cross-contaminant radionuclides including 134 Cs, 86 Rb, 124 Sb, 60 Co and 51 Cr was carried out onto small chro- matographic columns of the matrix (each of 1.0 g). Gamma-ray spectrometric analysis data showed that the purification process was not affected by either Mo(VI) concentrations (0.13 and 0.02 M Mo) in the feeding solu- tion of 3.5 M NaNO3 at pH 9.5 or flow rates (0.2 and 5.0 mL/min) at room temperature. Molybdenum(VI) aver- age loss onto the column matrix did not exceed 7.7 9 10 -2 mmol Mo. Except for 51 Cr, the matrix has very high selectivity for 134 Cs, 86 Rb and 124 Sb with *50% 60 Co elimination. The obtained data were briefly discussed. |
