PURPOSE:To dispose harmful living things with a low cost without environmental pollution, by carrying the intensifying material, which has the absorption band of a specific wave length and has a fixed value or more of dissolved oxygen consumption, as the absorbent of ion absorption treatment of harmful living things. CONSTITUTION:In case that the absorbent having the cation group is brought into contact with harmful living things such as viruses and mold to perform ion absorption treatment, the intensifying material such as eosin Y and rose bengal which has an absorption band in wave length region 380-800mm. and has 0.5 or more dissolved oxygen consumption DELTADO is carried on this absorbent. Then, the absorbent whose absorption capability is lowered after absorption treatment is subjected to photo- oxidation treatment under existence of oxygen to kill and remove harmful living things, and absorption capability of the absorbent is restored to reproduce the absorbent. Thus, harmful living things are disposed without repollution cheaply and simply. |
