Storing the anti-bacterial treatment water generation device and the phosphate buffered saline of the anti-bacterial treatment

摘要

PROBLEM TO BE SOLVED: To provide a method for producing antibacterially treated water including an antibacterial component selectively in a solution by utilizing a photocatalytic reaction.;SOLUTION: Titanium dioxide (IV), which is a photocatalyst 5 and to which halogen is chemically bonded, is fixed onto a filter. The titanium dioxide-fixed filter is brought into contact with a liquid 2 containing an oxo acid compound or a halogen compound. The fixed titanium dioxide (IV) is irradiated with ultraviolet light from a light source 6 while mixing an oxygen-including gas 3 in the liquid 2 by using a gas mixing means 8 to produce the antibacterial component of halogen oxides such as hypochlorous acid or active oxygen species such as hydrogen peroxide in a reaction solution. The antibacterial component is reacted with microbes such as bacteria, which are suspended in a liquid or stuck to the surface of a solid, to exhibit antibacterial treatment.;COPYRIGHT: (C)2011,JPO&INPIT
