摘要：
Sorption of Sr-85, Cs-137, and Eu-152 from neutral and acidic solutions on mixed hexacyanoferrates of potassium and uranyl K4(UO2)(4)[Fe(CN)(6)](3) center dot 4H(2)O and K-2 (UO2)(5)[Fe(CN)(6)](4)center dot 3H(2)O is studied. The distribution coefficients of Sr-85, Cs-137, and Eu-152 between the solid phase of K-2(UO2)(5)[Fe(CN )(6)](4)center dot 3H(2)O 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 K-4(UO2)(4)[Fe(CN)(6)](3)center dot 4H(2)O, 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 K-4(UO2)(4)[Fe(CN)(6)](3) 4H(2)O and the aqueous phase decrease with decreasing pH.
