    • A method of removing hydrogen peroxide from water, characterized by bringing hydrogen peroxide-containing raw water into contact with a hydrogen peroxide decomposition catalyst which comprises a support and, deposited thereon, nanocolloidal particles of a platinum-group metal having an average particle diameter of 1-50 nm. Also provided is an apparatus for removing hydrogen peroxide, characterized by comprising: a hydrogen peroxide decomposer packed with a catalyst which comprises a support and, deposited thereon, nanocolloidal particles of a platinum-group metal having an average particle diameter of 1-50 nm; a water supply means for supplying hydrogen peroxide-containing raw water to the decomposer; and a drainage means for discharging from the decomposer the water which has been contacted with the catalyst. By the method and apparatus, hydrogen peroxide contained in raw water can be rapidly removed without fail. They are suitable for removing hydrogen peroxide from ultrapure water in an apparatus for ultrapure water production which is used especially in an industry where electronic materials such as semiconductors and liquid crystals are handled.
    • 一种从水中除去过氧化氢的方法,其特征在于使含过氧化氢的原水与包含载体的过氧化氢分解催化剂接触,并沉积有平均粒径为1的铂族金属的纳米胶体颗粒 -50nm。 还提供了一种去除过氧化氢的装置,其特征在于包括:装有催化剂的过氧化氢分解器,其包含载体并沉积在其上的平均粒径为1-50nm的铂族金属纳米胶体颗粒; 用于向分解器供给含过氧化氢的原水的供水装置; 以及用于从分解器排出与催化剂接触的水的排水装置。 通过该方法和装置,原料水中所含的过氧化氢可以迅速地被除去。 它们适用于在用于超纯水生产的设备中从超纯水中除去过氧化氢,其特别用于处理电子材料如半导体和液晶的工业中。
