Ion Exchange of Cs Ion in Acid Solution with Potassium Cobalt Hexacyanoferrate
E-mail:
Potassium cobalt hexacyanoferrate (KCoFC) was synthesized for removal of Cs ions in acid waste solution. The synthesized KCoFC was stable in nitric acid solution of pH=1 and showed high selectivity for Cs ion over Sr and Na ions. The Kd,csfor 0.01 N Cs ion solution at pH=2 was about 3.6X103mL/g in the presence of the same concentrations of Sr and Na ions, respectively. In the binary ion exchange system, both the Dubinin-Polanyi model Langmuir model. However, in the multi-component system, only the modified Dubinin-Polanyi model, which is a semiempirical equation, fit the experimental data accurately. The ion exchange capacity of KCoFC for Cs ion obtained by the Dubinin-Polanyi equation was 1.72 meq/g
