摘要：
Using the methods of photocolorimetry, ion exchange and electron paramagnetic resonance, the chemical state of iron ions in the aqueous phases of suspensions of ultrafine iron powders was investigated. These powders are promising as plant growth stimulants. By studying the redox potentials of the system, it was demonstrated that the transition of iron into the solution depends on the acidity of the medium and the concentration of iron in the suspension.
