Description

Purification of alkaline solutions from Pu(4) trace amounts by precipitation of Fe(3) hydroxide appearing as a result of Fe(CN)5NO2- ion hydrolysis is studied by radiometric method. Pu(4) is coprecipitated effectively in 0.5-4 mol/l NaOH solutions. Inorganic and organic anions and complexones decrease purification coefficient values

Abstract (Russian)

Радиометрическим методом исследована очистка щелочных растворов от микроколичеств Pu(4) осаждением гидроксида Fe(3), возникающего при гидролизе Fe(CN)5NO2- иона. Pu(4) соосаждается эффективно в растворах 0,5-4 моль/л NaOH. Неорганические и органические анионы и комплексоны снижают коэффициенты очистки
