Fine-Dispersed Iron (III) Oxyhydroxides Synthesis: Carbamide Precipitation

The conditions of carbamide precipitation synthesis of fine-dispersed iron (III) oxyhidroxides from iron (III) sulphate and nitrate solutions were found out. In order to determine the necessary precipitant amount potentiometric precipitation titration of iron (III) sulphate and nitrate solutions with ammonia and hydrolyzed carbamide solutions were carried out. The results of these researches are expounded.
