In present work the regularities of electrochemical dissolution of iron with the participation of industrial three-phase AC 50Hz in aqueous solutions of HCl and H2SO4 were studied the first time. The features of the dissolution of iron electrodes at polarization with alternating current in acid solution to form ions of iron (II) were studied and the influence of various factors was examined. Based on the study results a new and efficient method of synthesis of iron salts which are widely used as a coagulant in water treatment was proposed.
