Composition and exchange capacity of colloid iron (III) oxyhydrate at hydrolysis and extraction

The models of formation function for iron oxyhydrate sol in chloride systems have been suggested, that are based upon solubility product equation and ion exchange isotherm, as well as Lange-Berg adsorption equation. The sol exchange capacity, found during modeling, explains the existence of Fe(OH)2,75(An)0,25 aqueous colloids and Fe(OH)2,75Х1/6Cl1/12 organosol. It has been shown that the sol exchange capacity is determined by the configuration of active centers upon the micelle surface.
