FUNCTIONAL WATER, METHOD AND DEVICE FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide functional water with excellent cleaning efficiency by electrolyzing an electrolytic solution containing fluoride ion with efficiency higher than that in conventional electrolysis. SOLUTION: The functional water is characterized by including a fluorine containing component obtained by electrolyzing an aqueous solution containing fluoride ion by using an electrode having conductive diamond. The fluorine containing component generated by electrolyzing fluoride ion by using the conductive diamond electrode has a cleaning effect more powerful than that exhibited by fluoride ion itself before electrolysis or that exhibited by the fluorine containing component obtained by electrolyzing fluoride ion by using other electrodes and thereby remarkably reduces quantity of hydrofluoric acid consumed.
