Embodiment 1

[0154]

[0155] Dissolve the commercially available SBT method available chlorine test piece 6mm×6mm, the commercially available universal test piece 6mm×6mm, and 1 mg of syringaldazine in 1ml of dimethylformamide, and dilute it with 10ml of methanol to obtain Spray the liquid evenly on the A4 drawing paper, make the solvent volatilize, make test paper, cut out 6mm×6mm paper pieces from it, and paste them on the 6mm×50mm paper pieces with double-sided tape in turn to make a test paper. Test paper of the present invention.

Embodiment 2

[0157]

[0158] According to the prescription shown below, the prescription ingredients were mixed with a Henschel mixer for 10 minutes, weighed 1 g, and compressed with a tablet machine to obtain tablets. Dissolve this tablet with tap water 5l, the result dissolves immediately, about solution, judge with the test paper of embodiment 1, the result pH is 6.5, and the concentration of hypochlorous acid is 100ppm, and the free chlorine molecule concentration just after dissolving is 0.2ppm. It has almost no peculiar smell.

[0159] [Table 1]

[0160]

Embodiment 3

[0162] In this embodiment, the mixing time in the preparation of the tablet of Example 2 was set to 3 minutes, and all the other operations were performed in the same manner as in Example 2. Measure for solution with the test paper of embodiment 1, result pH is 7.5, and available chlorine concentration is 100ppm, and free chlorine molecule surpasses 10ppm, exceeds specification. After dilution, the colorimetric measurement was carried out within the scale, and the result was 20ppm. The irritating odor of this substance is strong.

Abstract

Provided is an effective method for removing pathogens such as pathogenic viruses that are highly resident in a living space. Hypochlorous acid water has a pH of 5 to 7.5, and a concentration of free chlorine molecules is lower than an effective chlorine concentration,.

Description

technical field [0001] The present invention relates to hypochlorous acid water and a composition used for virus eradication, and more specifically, to a composition for virus eradication excellent in storage stability. The present invention relates to a test paper for accurately determining the effectiveness and toxicity of hypochlorous acid, which is a composition for removing pathogens, and more specifically, relates to an effective and safe hypochlorous acid composition proved by the test paper. Background technique [0002] Removal of pathogens such as viruses is an important technique for prognostic measures and preventive measures of infectious diseases caused by pathogens. So far, disinfection has been carried out by fumigation with ethanol or formalin, general-purpose fungicides mainly composed of hypochlorite, and the like. However, the method of safely sterilizing the entire room has not been known until now, and the method of spraying electrolytic hypochlorous a...
