The invention discloses a hypochlorous acid solution stabilizer. The hypochlorous acid solution stabilizer is any one or more of chitosan, cyclodextrin, polyol, a surfactant and sulfamate. The invention also discloses application of the hypochlorous acid solution stabilizer in improving the stability of a hypochlorous acid solution. The invention also discloses a method for promoting the stabilityimprovement of the hypochlorous acid solution. The method comprises the following steps: 1) preparing a hypochlorous acid initial solution; and 2) adding the hypochlorous acid solution stabilizer into the hypochlorous acid initial solution. The invention also discloses the hypochlorous acid solution. The effective chlorine content of the prepared product is 68 mg / L + / -15%, the pH value is 5.0-7.5, the reduction rate of effective chlorine is as low as 10%, and the method has industrial production and practical application value.
Description
technical field [0001] The invention belongs to the technical field of hypochlorous acid solution production, and relates to a hypochlorous acid solution stabilizer and its application. Background technique [0002] At present, the methods for producing hypochlorous acid water include pH adjustment method and electrolysis method. The pH adjustment method is formed by diluting hypochlorite with citric acid or hydrochloric acid. The content of acid radicals is high, and the bactericidal effect is not as good as the hypochlorous acid solution prepared by electrolysis. [0003] The electrolysis method is generated by electrolysis of chlorine salt or hydrochloric acid or a mixture solution of hydrochloric acid and chloride salt. The hypochlorous acid solution produced by these two methods has poor stability and cannot be stored for a long time. In the prior art, the patent CN110952108 adds a stabilizer to the hypochlorous acid solution prepared by electrolysis to improve its st...
