More specifically, the present invention relates to a sterilization/deodorization composition and a sterilization/deodorization method that can generate chlorine dioxide in gaseous form to sterilize and deodorize various electrical objects present in the atmosphere.

る。Therefore, we have conventionally used two types of solid compounds that can react in water to generate chlorine dioxide, and by adding these to water at the time of use, we can avoid generating chlorine dioxide on the spot and act on various objects in the atmosphere. Sterilization and deodorization methods are known. As a drug for carrying out such a method, for example, a solid composition combining hypochlorite and chlorite was proposed (Japanese Patent Publication No. 19561/1983), and a combination of hypochlorite and citric acid was proposed. There is a proposal to combine it with an organic acid such as

There was a tendency for the chlorine dioxide generating ability of such a prepared solution to decrease in a short period of time (within I days). As a result, although sterilization and deodorization abilities are expressed immediately after preparation, the effects do not last long, and are used in applications that require relatively long-term sterilization and deodorization effects, such as refrigerators and fruit storage boxes. However, it was not satisfactory for use in sterilizing and deodorizing fish boxes and the like.

いｒこ。In particular, in refrigerators and fruit storage boxes, C10t is usually 0.000% in the atmosphere for sterilization and air purification.
From the viewpoint of effectiveness and toxicity, it is desirable that the concentration be maintained at about 1 to 005% (I to 500 ppm), and that this concentration be maintained for a certain period of time, and that the concentration should not decrease after this period and remain in the system. . However, when conventional solid compositions for generating chlorine dioxide are used, a large amount of chlorine dioxide is initially generated and the period for which the above concentration is maintained is extremely short, especially after sterilization of several days to several weeks. This poses a major problem when used in the above-mentioned target systems where deodorization is desired.

More specifically, it is preferable that the ratio of chlorite and sulfur-containing oxygen salt used is l:o, ol to lO by weight, and by adjusting this ratio, the generation concentration and generation period can be controlled. You can also do it.

便利である。The sterilization/deodorization method of the present invention involves storing an aqueous medium such as water in a suitable container, adding and dissolving both of the above-mentioned components in the aqueous medium to generate chlorine dioxide, and then using the container to sterilize or deodorize. This can be done by placing an appropriate number of them in or near the object to which the odor is intended. Alternatively, the above reaction can be carried out in a gas-permeable plastic bag to generate chlorine dioxide, and a suitable number of the bags can be placed in or near the object. In particular, a double-structured bag is used, in which a gas-permeable outer bag houses an easily tearable inner bag containing the sterilizing/deodorizing composition of the present invention and an aqueous medium, and the inner bag is removed by hand during use. By tearing the container, both of the above-mentioned components are dissolved in an aqueous medium to generate chlorine dioxide, and the generated chlorine dioxide is released to the outside through the outer bag, which is convenient in terms of handling.

また使用後の二酸化塩素の残留も防止される。In this invention, the reaction between the chlorite and the sulfur-containing oxygen salt is carried out smoothly at room temperature, thereby generating chlorine dioxide. This chlorine dioxide generation reaction is not rapid as in the conventional case, but proceeds relatively slowly. Therefore, chlorine dioxide is generated stably for a long time, and 1
Stable sterilization and deodorizing effects can be achieved for a long period of time, from about a day to two weeks, and in some cases up to about a month.
It also prevents chlorine dioxide from remaining after use.

この結果は第１図（ハ）に示されるごときてあり、２〜
３ ｐｐｍの二酸化塩素が約１週間安定して放出される
ことが判る。The results are as shown in Figure 1 (c), and 2-
It can be seen that 3 ppm of chlorine dioxide is stably released for about one week.
そして、上記いずれの実施例において乙、反応終了後に

ことが判る。As shown in these examples, the sterilization and
The deodorizing composition has the ability to generate chlorine dioxide for a longer period of time than conventional ones, and by changing the concentration ratio of chlorite and sulfur-containing oxygen salt, the deodorizing composition can generate chlorine dioxide. It can be seen that the chlorine generation period and release concentration can be adjusted. Therefore, it can be seen that the chlorine dioxide release ability can be adjusted depending on the use and duration of action.
