Title: Solid agent for preparing water to be electrolyzed
Inventor: HOSHINO MASAHARU
IPC: C02F1/46
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To prepare water to be electrolyzed which is necessary for preparing electrolyzed water suitable for disinfection even after being left open for one day and which can be prepared, at one time, in an amount enough for the use in one day by using a solid agent containing a chloride and an acid selected from among succinic, malic, and tartaric acids. SOLUTION: This solid agent for preparing water to be electrolyzed contains a chloride and an acid selected from among succinic, malic, and tartaric acids. Though there are powdery acids, such as citric, ascorbic, and fumaric acids, other than above, a solid agent containing an acid selected from among these acids is not favorable since it is hardly soluble in water and it gives water to be electrolyzed which, when electrolyzed, gives electrolyzed water which, when left open for one day, the concentration of effective chlorine remaining in the electrolyzed water becomes zero. The chloride is sodium chloride, calcium chloride, potassium chloride, magnesium chloride, or the like, and sodium chloride being preferable. The solid agent is mixed with a certain amount of water, such as tap water, pure water, RO water or distilled water, to prepare water to be electrolyzed.
