To sum up, the utility model provides a chlorine dioxide slow-release bag. The chlorine dioxide slow release package consists of an inner reactant and an outer packaging bag which hermetically wraps the inner reactant; the outer packing bag is of a double-layer structure formed by compounding a cloth outer layer and a hydrophobic membrane inner layer. The size of the cloth outer layer is consistent with that of the hydrophobic membrane inner layer, and the cloth outer layer and the hydrophobic membrane inner layer are stacked and sealed along the edges. The inner reactant is composed of chlorine dioxide precursor substances, acidic substances and water-absorbing substances. The chlorine dioxide slow-release package can be applied to water body disinfection to obtain stable chlorine dioxide solution with the purity of 99.99 percent, and has excellent disinfection and sterilization effects; also can be used as gas slow release to achieve the effects of air disinfection and aldehyde removal. The chlorine dioxide slow-release package is simple to manufacture, convenient to transport and wide in application range.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; these modifications and substitutions do not depart from the essence of the corresponding technical solutions of the embodiments of the present invention.
