Document Type and Number:
Japanese Patent JP4920019
Kind Code:
B2
Abstract:
To provide a method and a device for reducing hydrogen peroxide which can rapidly and certainly treat hydrogen peroxide in water to be treated with a catalyst resin carrying a small amount of a catalyst metal, and to provide an ultrapure water manufacturing device including the above device.
In the method for reducing hydrogen peroxide in the water to be treated by bringing the catalyst resin in which a catalyst metal having the decomposability of hydrogen peroxide is carried on an anion exchange resin into contact with the water to be treated containing hydrogen peroxide, 70% or more of the total exchange volume of the anion exchange resin are of an OH-type.
