Centrifugal extraction machine hydrometallurgy hydrogen evolution over potential
Centrifugal extraction machine hydrometallurgy hydrogen evolution over potential, in the process of the development of the electrode process kinetics, the precipitation of hydrogen are most of the electrode reaction.
Experiment found that the precipitation of many hydrogen electrode reaction have been accompanied by a larger potential.
for electrolytic production in aqueous solution, hydrogen evolution over potential has great practical significance.
Such as hydrogen preparation from electrolysis of water or heavy water, higher hydrogen CLP to consume large amounts of electric energy, increase the cost of production.
For aqueous solution of non-ferrous metal electrolysis, centrifugal extraction machine hydrometallurgy hydrogen evolution over potential, high hydrogen life is set here is very good.
