Embodiment 1

[0037] Weigh disodium edetate, citric acid and lactic acid for later use, mix 30% hydrogen peroxide solution, disodium edetate, citric acid, lactic acid and water in a stainless steel reaction vessel, stir , prepared into hydrogen peroxide with a volume concentration of 5.0%, disodium edetate with a mass concentration of 0.02%, citric acid with a mass concentration of 0.05%, and lactic acid with a mass concentration of 0.05%, supplemented to 100% with water to obtain 5.0% Hydrogen peroxide compound disinfectant.

Embodiment 2

[0039] Weigh disodium edetate, citric acid and lactic acid for later use, mix 30% hydrogen peroxide solution, disodium edetate, citric acid, lactic acid and water in a stainless steel reaction vessel, stir , be prepared into hydrogen peroxide with a volume concentration of 7.0%, disodium edetate with a mass concentration of 0.005g / L, citric acid with a mass concentration of 0.2%, and lactic acid with a mass concentration of 0.2%, supplemented to 100% with water to obtain 7.0% hydrogen peroxide compound disinfectant.

Embodiment 3

[0041]Weigh disodium edetate, citric acid and lactic acid for later use, mix 30% hydrogen peroxide solution, disodium edetate, citric acid, lactic acid and water in a stainless steel reaction vessel, stir , prepared into hydrogen peroxide with a volume concentration of 5.5%, disodium edetate with a mass concentration of 0.015%, citric acid with a mass concentration of 0.07%, and lactic acid with a mass concentration of 0.07%, supplemented to 100% with water to obtain 5.5% Hydrogen peroxide compound disinfectant.

Abstract

The invention provides a compound hydrogen peroxide disinfectant which is prepared from the following ingredients by percentage composition: hydrogen peroxide with the volume concentration of 5.0-7.0%, disodium edta with the mass concentration of0.05-0.02%, citric acid with the mass concentration of 0.05-0.15%, lactic acid with the mass concentration of 0.05-0.15% and the balance of water replenished until the total percentage is 100%. <0}Sterilization-enhancing agents, namely the citric acid and the lactic acid are added into a hydrogen peroxide solution, meanwhile the disodium edta is added as a complex stabilizer, and the citric acid is also a complex stabilizer, so that long-term stability of the hydrogen peroxide disinfectant is kept, and the quality guarantee period is one year. <0}The compound hydrogen peroxide disinfectant is low in effective use concentration, relatively low in residual toxicity and free from dilution, and is convenient to apply since a stock solution can be directly used for disinfection.

Description

technical field [0001] The invention belongs to the field of bactericidal disinfectants, and in particular relates to a compound disinfectant and its preparation method and application. Background technique [0002] Disinfectant is a colorless liquid with a strong pungent odor. It is used to kill pathogenic microorganisms on the transmission medium to make them harmless, eliminate pathogenic microorganisms outside the human body, cut off the transmission route of infectious diseases, and achieve the purpose of controlling infectious diseases. In recent years, countries have focused on searching for environmentally friendly and fast-acting disinfectants, among which hydrogen peroxide and chlorine dioxide gas sterilization methods have attracted more attention, and ozone disinfection also has broad use value. There are many types of disinfectants, commonly used types include potassium permanganate, formaldehyde, glutaraldehyde, ethylene oxide, peracetic acid, hydrogen peroxid...
