CONCENTRATED SOLUTION OF ACTIVE OXYGEN ELIMINATING AGENT, METHOD OF PRODUCING THE SAME AND ACTIVE OXYGEN ELIMINATING AGENT POWDER

摘要

PROBLEM TO BE SOLVED: To provide a concentrated solution of an active oxygen eliminating agent having strong and stable active oxygen eliminating activity. SOLUTION: A hydrogen adsorbent is added to pure water containing an electrolyte. Pure water containing the hydrogen adsorbent is introduced into cathode and anode chambers partitioned by a diaphragm. A cathode is disposed in the cathode chamber and an anode is disposed in the anode chamber and electricity is applied across the cathode and the anode to electrolyze the pure water and the electrolytically reduced water in the cathode chamber is taken out and evaporated to be concentrated.
