Study of the Influence of Nonequilibrium Dielectric-Barrier Discharge Plasma on the Valence State of Transition Metals in Aqueous Solutions
- 30 Downloads
The effect of dielectric-barrier discharge plasma treatment on the valence state of metal ions in aqueous solutions of manganese, iron, cobalt, and nickel (Mn, Fe, Co, Ni) salts has been studied. The efficiency of recovery of sparingly soluble compounds of transition metals during the treatment of model solutions in a plasma reactor designed by the authors has been evaluated. The possibility of hydrogen peroxide formation in water by barrier discharge treatment has been shown, and the change in the redox potential of the system has been analyzed.
