Description

One studied the effect of various factors on the coprecipitation of cesium trace amounts with nickel ferrocyanide precipitate. The precipitate was separated via filtration through the materials differing in pore size. One determined the optimal conditions for the process to remove cesium radionuclides from the solutions: the filtering material pore size was maximum 0.2 μm; Ni2+/Fe(CN)64- molar ratio = 1.33-1.75; (NaNO3) electrolyte concentration was minimum 0.05 mole/l; solution pH - maximum 10

Abstract (Russian)

Исследовано влияние различных факторов на соосаждение микроколичеств цезия с осадком ферроцианида никеля. Осадок отделяли путем фильтрации через материалы с различным размером пор. Определены оптимальные условия процесса очистки растворов от радионуклидов цезия: размер пор фильтрующего материала не более 0.2 мкм; мольное соотношение Ni2+/Fe(CN)64- = 1.33-1.75; концентрация электролита (NаNО3) не менее 0.05 моль/л; рН раствора не более 10
