چکیده:

Potassium hexacyanocobalt (II) ferrate (II) was prepared and dried at high temperatures and then characterized by chemical analysis, X-ray diffraction, Inductively Coupled Plasma and infrared. The ion exchange properties of alkaline earth metals on a nonstoichiometric compound K2[CoFe(CN)6] was examined by batch methods. The distribution coefficient values (Kd)] for alkaline earch metals showed the following trend Ba2+>Sr2+>Ca2+>Mg2+>, which is the same as the order of the size of the hydrated cations
