Abstract

Procedure for the preparation of pure aqueous solutions of sodium hexacyanoferrate-III-or potassium hexacyanoferrate-III-sodium by electrolytic oxidation or by oxidation with hydrogen peroxide, oxygen or air and neutralization of the resulting hydroxide, characterized in that solutions of sodium hexacyanoferrate-II-Na4 [Fe (CN) 6] or a mixture of a solution of one equivalent of sodium hexacyanoferrate-II-potassium and a solution of two equivalents of potassium hexacyanoferrate-II-K4 [Fe (Cn) 6] for the preparation of Na3 [Fe (CN) 6] or of K2Na [Fe (CN) 6] and because for neutralization hexacyanoferrate-II-ico acid or hexacyanoferrate-III-ico acid are used.
