Abstract
The invention provides a novel electric potential water disinfectant and a preparation method thereof. The disinfectant with pH of 4-6 and the redox potential of 800-1200 mV is prepared by employing a special electrolytic tank and sodium chloride for electrolysis. The disinfectant is applicable to disinfection of surfaces of hospital objects and environment, and original-liquid immersing disinfection. The disinfectant has no toxicity and no simulation to human body, animals and organisms, is low in metal corrosion capability, low in hypochloric acid concentration (40-80 ppm), free of residues and free of environmental pollution, and has obvious killing effect on pathogenic bacteria, candida, salmonella, escherichia coli and the like when being used at a low concentration (50-80 ppm).
Description
Art
The present invention relates to novel current potential aqueous disinfectant of a kind of non-toxic efficient and preparation method thereof.
Background technology
Disinfectant management is the important measures controlling hospital infection and improve public health security.At present general in prevent nosocomial infection and have heat sterilizer, chemical sterilization, aerosol sterilization method and ultraviolet sterilization to the environment conventional method that carries out disinfection in the world, chemosterilant is owing to having the advantages such as wide in variety, sterilizing operation convenient, disinfection apparatus is simple and applied widely. in the daily sterilization of hospital and the sterilization of environment, there is very important status.Chemicals relatively more conventional is at present mainly glutaraldehyde, phenol, the tincture of iodine, cresols, clorox, ethanol and highly acid electrolyzed oxidizing water.Desirable bactericidal agent should be that fungicidal spectrum is wide, and effect fast; Stable performance, is convenient to store and transport; There is no toxicity and excitant, there is no the environmental pollution that medicament residue causes yet; Little by organic matter, soda acid and such environmental effects; Activity is low, easy to use, cheap, but does not have a kind of chemosterilant can meet the standard of preferred disinfectants so far.
Summary of the invention
The present invention is intended to overcome the deficiencies in the prior art, provides a kind of novel current potential aqueous disinfectant of non-toxic efficient.
Prepare this novel current potential aqueous disinfectant, pass through following steps:
1) pass through without the special electrolytic cell of barrier film, its outer wall both sides are positive pole, and central electrode is negative pole, by constant displacement pump, sodium chloride solution is injected electrolytic cell, and regulates concentration, and sodium chloride is by electrolytic ionization Na
+, Cl
-.
2) Na
+the electronics discharged at positive pole by obtaining chlorion is converted into sodium.The sodium generated reacts at dilution trap and water and generates hydrogen and sodium hydroxide.
3) chlorion moving to positive pole is converted into chlorine by release electronics, and the chlorine of generation reacts with water and generates hypochlorous acid and hydrochloric acid in mixed diluting groove.
This novel current potential aqueous disinfectant, physics and chemistry feature: PH4-6, redox potential at 800-1200mV, effective chlorine density 40-80ppm.
This non-toxic efficient electric potential water disinfectant, has good stability, has obvious lethal effect to multiple common clinical pathogenic bacteria.Following experimental example is used for further illustrating the present invention, but does not limit the present invention in any way.
