METHOD FOR PRODUCING ACTIVE HYDROGEN-CONTAINING WATER BY MAGNETIC TREATMENT

摘要

PROBLEM TO BE SOLVED: To provide a method for producing active hydrogen-containing water by subjecting water to magnetic treatment, wherein active hydrogen-containing water, for example, prevents red rust from being generated on the surface of iron in a water pipe and chemically deoxidizes hematite (FeO(OH)) being red rust, which is stuck to or generated on the surface of iron in the water pipe, into magnetite (Fe3O4) being black rust to make the surface of iron in the water pipe corrosion-proof and rustproof. SOLUTION: The active hydrogen-containing water is produced by subjecting water to the magnetic treatment (for example, by imparting a magnetic field of 100-15,000 gauss magnetic flux density to water only once or two or three times repeatedly) in magnetic treatment apparatuses 4a, 4b each using a permanent magnet. The concentrations of various kinds of excited and activated hydrogen (an excited hydrogen molecule (DH), an excited hydrogen ion (H+) and an excited hydrogen atom (H*)) in the active hydrogen-containing water are measured to determine the magnetic treatment capacity quickly and easily, which used to require long-term work.
