Abstract:

The effect exerted on the selectivity of hydrated TiO2 to Sr by surface modification of the sorbent involving immobilization of mixed nickel potassium ferrocyanide was studied. The Sr specificity of the resulting sorbent (denoted as T-55) is comparable with that of hydrated TiO2: logK d (K d is Sr distribution coefficient, ml g-1) is 2.7 ± 0.2 in sorption from tap water with pH 7.8 ± 0.2, 2.7 ± 0.5 in sorption from CaCl2 solutions with pH 5.6 ± 0.2, and from 2.5 ± 0.8 to 1.7 ± 0.4 in sorption from CaCl 2 solutions with pH 7.0 ± 0.2. The modification makes the resulting T-55 sorbent selective to Sr in the presence of Ca at pH 5-6. © 2013 Pleiades Publishing, Ltd.
