A novel method of electrochemical treatment such as electroplating, etc. and an electrochemical reaction apparatus thereof which is high in reactability and able to be electrochemically reacted efficiently, which is small or zero in amount of generation of liquid waste such as electrolytic solution and cleaning liquid and therefore, amicable to the environment, and in which it is no more required to clean the electrode, etc. with cleaning liquid after reaction. Electrochemical reaction is executed in a reaction vessel (6) containing matter (5) which is in a supercritical or subcritical state and an electrolytic solution (1), and after reaction, the supercritical or subcritical matter (5) is shifted into a state of the matter (5) before being shifted into a critical state.
A method of electrochemical treatment comprising introducing an electrode, a substance which is in a subcritical state, and small amounts of electrolytic solution and, for emulsification purpose, surfactant into a reaction vessel such that said electrode is not in contact with said electrolytic solution, thereafter shifting said substance into a supercritical state, and electrolyzing said electrolytic solution thereby to effect electrochemical reaction, and said electrolytic solution being in uniformly emulsified condition when said electrochemical reaction takes place.
A method of electrochemical treatment comprising introducing an electrode, a fluid which is in a subcritical state, and small amounts of electrolytic solution and, for emulsification, surfactant into a reaction vessel such that said electrode is not in contact with said electrolytic solution, thereafter pressurizing said reaction vessel to a level equal to or higher than atmospheric pressure but not higher than supercritical pressure of said fluid, and electrolyzing said electrolytic solution thereby to effect electrochemical reaction, said fluid and said electrolytic solution being in uniformly emulsified condition when said electrochemical reaction takes place.
An apparatus for electrochemical reaction, the apparatus comprising a reaction vessel and an electrode received in the reaction vessel, the reaction vessel being adapted to receive a substance which is in a subcritical state and small amounts of electrolytic solution and, for emulsification purpose, surfactant, said apparatus being configured so that said electrolytic solution is received in said reaction vessel without contacting said electrode, means for shifting said substance in said reaction vessel into a supercritical state, and means for electrolyzing said electrolytic solution when said substance and said electrolytic solution are in uniformly emulsified state so that electrochemical reaction takes place.
An apparatus for electrochemical reaction comprising a reaction vessel, an electrode received in said reaction vessel, said reaction vessel being adapted to receive a substance which is in a subcritical state and small amounts of electrolytic solution and, for emulsification purpose, surfactant, for emulsification purpose, Without said electrolytic solution contacting said electrode, means for pressurizing said reaction vessel to a level equal to or higher than atmospheric pressure but not higher than critical pressure of said substance, and means for electrolyzing said electrolytic solution when said substance and said electrolytic solution and in uniformly emulsified state so that electrochemical reaction takes place.
