An electrochemical system is studied in which one
electrode is in the vapor phase over a liquid
surface and the other is under the liquid surface,
and a non-self-maintained glow discharge initiated
by a subsidiary discharge burns between the upper
electrode and the liquid surface. It is shown that
in this system ions of heavy metal compounds are
released from solution within a relatively thin
near-surface layer of the solution. Conditions are
found under which the efficiency of plasma chemical
extraction of metals from the solutions is several
times higher in comparison with the electrochemical
method.
