A thermodynamic model of the mixed-salt cobalt(II)–hexacyanoferrate(II) ion exchanger
Abstract
A thermodynamic model for the ion exchange of K, NH4 and Cs on the ion exchanger cobalt(II)–hexacyanoferrate(II)–M where M = K,NH4 and Cs, has been postulated. Based on the experimentally determined thermodynamic functions ΔG⊖exp, ΔS⊖exp and ΔH⊖exp and on the calculated values of excess functions, the deviations from ideality of the investigated reactions have been explained.
