Sorption of 85Sr, 137Cs, and 152Eu from neutral and acidic solutions on mixed hexacyanoferrates of potassium and uranyl K4(UO2)4[Fe(CN)6]3 · 4H2O and K2(UO2)5[Fe(CN)6]4 · 3H2O is studied. The distribution coefficients of 85Sr, 137Cs, and 152Eu between the solid phase of K2(UO2)5[Fe(CN)6]4 · 3H2O and the aqueous phase are determined to be 210±10, 3000±500, and 1100±250 ml g?1, respectively, at a contacting time of 120 min. For solid K4(UO2)4[Fe(CN)6]3 · 4H2O, the respective values are 6670±900, 5600±300, and 3300±250 ml g?1. The 85Sr, 137Cs, and 152Eu distribution coefficients K d between the solid K4(UO2)4[Fe(CN)6]3 · 4H2O and the aqueous phase decrease with decreasing pH.
