Формы нахождения железа (III) в водных растворах солей сильных неорганических кислот

Abstract

The possible ionic equilibria in FeCl3 aqueous solutions were considered and the most probable of them were determined. Mathematical model of complexation was developed. The process of iron (III) transformation to the required complex form by mathematically predicted change of solution composition was shown. The targeted recharge of complex particles was used as a basis for separating iron (III) and heavy nonferrous metals based on the available ion-exchange resins.
