Abstract

PROBLEM TO BE SOLVED: To increase the oxidative capability by jointly using hydrogen peroxide and a ceramic carrying a hydrogen peroxide activating catalyst. SOLUTION: This advanced oxidation method consists of bringing hydrogen peroxide into contact with a ceramic carrying a hydrogen peroxide activating catalyst to treat an object to be treated. The hydrogen peroxide activating catalyst is formed from such transition metals at Pt, Ru and Rh, their oxides, hydroxides or salt. The ceramic is made from one or plural kinds among kaolinite, montmorillonite or the like. The advanced oxidation is carried out by previously admixing hydrogen peroxide with a liq. to be treated and bringing the admixture into contact with the ceramic. The content of the hydrogen peroxide activating catalyst in the ceramic material is controlled to 1.0-30 wt.% to make the reaction with hydrogen peroxide effective and to enhance the treating effect such as sterilization.

2. Description of the Related Art Conventionally, hydrogen peroxide has an oxidizing power,
It has been used as a bactericide or as a treating agent for decolorization and deodorization in the pulp and fiber manufacturing industries and in other industrial fields. However, the use of hydrogen peroxide alone has its own oxidizing power, and when it is used as a disinfectant or the like, its processing capacity is limited. Therefore, some advanced oxidation treatment methods using a "system using hydrogen peroxide" have been proposed.
