Embodiment 1

[0077] Present embodiment provides a kind of sporicide (totally 100g), and its formula is as follows:

[0078] (1) 80% sodium chlorite 1.25g;

[0079] (2) 50% hydrogen peroxide 5g;

[0080] (3) 001 × 7 type cation exchange resin, the pH value of regulating the sporicide is 3.5;

[0081](4) The remainder is water.

Embodiment 2-3

[0083] The formula is shown in Table 3.

Embodiment 4～6

[0085] The present embodiment provides the preparation method of the sporicide described in the foregoing embodiments 1-3, and prepares the sporicide of Example 1-3 according to the composition of Table 3, and the specific preparation steps are as follows:

[0086] (1) Get sodium chlorite, add appropriate amount of solvent listed in Table 3, stir to dissolve, make solution;

[0087] (2) Add the pH value of the pH adjusting agent listed in Table 3 to adjust the solution (if using ion exchange resin to adjust pH, the ion exchange resin should be removed by filtration after the pH reaches the requirements);

[0088] (3) adding hydrogen peroxide as antioxidant;

[0089] (4) Stir evenly to make a transparent solution;

Abstract

The invention relates to sporicide as well as a preparation method and application thereof. The sporicide comprises the following components in percentage by weight: (1) 0.05 to 5 percent of chlorite;(2) 0.1 to 10 percent of a hydrogen peroxide antioxidant; (3) a pH regulator; and (4) the balance of a solvent, wherein the use amount of the pH regulator meets the requirement that the pH value of the sporicide is 3 to 6. The invention also relates to a preparation method and application of the sporicide. The sporicide is microscopically acidic and does not contain a large amount of strong electrolyte, so that the problem that the chlorite is unstable under the acidic condition and the problem of low disinfecting and sterilizing activity are solved successfully; meanwhile, an excellent disinfecting and sterilizing effect is generated, and the sporicide can be widely applied to disinfection or sterilization of various object surfaces and closeable spaces (such as hospital operating rooms,production enterprise workshops, isolators, laboratories and biological safety cabinets).

Description

technical field [0001] The invention relates to the technical field of disinfection, in particular to a sporicide composed of chlorite and hydrogen peroxide antioxidant and its preparation method and application. Background technique [0002] Disinfectants refer to chemical preparations used to kill pathogenic microorganisms on the transmission medium to make them harmless. Sporicide is a disinfectant that can kill spores and spores. Currently commonly used sporicides are divided into peroxide sporicides (such as hydrogen peroxide and peracetic acid, etc.), active chlorine sporicides (such as hypochlorous acid / sodium and chlorine dioxide, etc.), and aldehydes. Sporicides of similar substances (such as formaldehyde, glutaraldehyde and o-phthalaldehyde, etc.), are commonly used for space disinfection and sterilization by atomization or vaporization. [0003] When using a single-component peroxide sporicide for space disinfection and sterilization by atomization or vaporizati...
