A kind of preparation method of acidic high oxidation water
Technical field
The present invention relates to acidic high oxidation water, specifically relate to a kind of preparation method of high oxidation water, do not contain chlorion in the high oxidation water of the present invention's preparation.
Background technology
Function water has another name called brine electrolysis, be through after the purifying treatment with ordinary tap water, add the NaCl (also can add KCl or hydrochloric acid) of a certain amount of (below 0.1%), utilize electrolysis principle (redox reaction), electrolysis is carried out in energising in being provided with the electrolyzer of ion exchange membrane, and wherein, anode side is to analyse chlorine reaction and oxygen evolution reaction, cathode side is based on evolving hydrogen reaction, in the solution then with the hydrolysis of chlorine with hypochlorously be dissociated into the master.Contain H from the effusive water of anode electrolytic cell side
+, the positively charged position, slant acidity is called acidic oxidized electric potential water (electrolized strong acid water); Contain OH from the effusive water of electric tank cathode side
-, having negative potential, meta-alkalescence is called alkaline reduction current potential water (electrolized strong alkaline water), claims alkaline ion water again.More than two kinds of water be referred to as oxidation-reduction potential water, all have higher redox potential.
Acidic oxidized electric potential water is colourless, transparent liquid, pH value 2.3~2.7, dissolved chlorine concentration 20~50ppm (low residue), redox potential (ORP)+1100mV, ingress of air, light, organism, or heat to being reduced into ortho-water gradually more than 40 ℃.Acidic oxidized electric potential water has convergence and bleaching action, and microorganisms such as bacterium are had the moment killing effect.
The Japanese the earliest loose tail of acidic oxidized electric potential water begins one's study in nineteen eighty-two to people such as rolling grade, mainly contains about its sterilization mechanism:
The physics theory:
Mainly comprise redox potential theory, electron motion theory and conductivity theory etc.Former people in 1994 generally accept Becking and say at the physical chemistry of nineteen sixty proposition: the low pH (below 2.7) of acidic oxidized electric potential water and high ORP (more than+1100mV) have exceeded the scope of microorganism, and the membrane potential of microorganism cells is changed, to cause the destruction of permeability of cell membrane enhancing and cellular metabolism enzyme, reach the argumentation of killing microorganisms.
Chemical theory (available chlorine theory):
Japanese scientist in 1994 has proposed low pH and high ORP is not the germ-resistant principal element of acidic oxidized electric potential water, and its germ-resistant main component comprises: hypochlorous acid, hydrogen peroxide and OH base.What is interesting is that these compositions are identical with the composition of the active oxygen of undertaking the neutrophil leucocyte germicidal action.Through a large amount of scientific experiments, the available chlorine theory had obtained confirmation in 1998, and having established the available chlorine in the acidic oxidized electric potential water is the main factor of pathogenic microbe killing.
Yet, point out that as JP 35487/1993 preparation of brine electrolysis is to be cost to expend a large amount of electric energy, and must produce the brine electrolysis of two kinds of current potentials during electrolytic reaction simultaneously, can not make a kind of function water wherein separately.Simultaneously, owing to need to add electrolytic agent, still can contain a certain amount of chlorion in the brine electrolysis of preparing.
Summary of the invention
The purpose of this invention is to provide a kind of and produce acidic oxidized electric potential water, do not produce the acidic high oxidation water preparation method of alkaline reduction current potential water, do not contain chlorion in the acidic high oxidation water of the present invention's preparation.
Acidic high oxidation water outward appearance provided by the invention is consistent with ortho-water, colorless and odorless, and after testing, its pH value is 1.0~2.0, redox potential is 200mV~350mV.
The concrete preparation method of acidic high oxidation water of the present invention is that Xiang Shuizhong feeds O
3And abundant aeration, make the redox potential of water reach 200mV~350mV, the pH value reaches 1.0~2.0, obtains acidic high oxidation water.
Wherein, employed water can be common tap water, also can be deionized water, all can obtain acidic high oxidation water of the present invention.
Feed O at Xiang Shuizhong
3The time, we find that when just beginning, the redox potential of water is to change to the negative potential direction earlier, when redox potential be reduced to-60~-promptly no longer reduce behind the 80mV, then beginning changes to the positive potential direction, until reaching 200mV~350mV.
Through validation trial, relatively more suitable condition is to prepare acidic high oxidation water of the present invention: with 1.5~2m
3The flow of/h feeds the O of 60~80mg/L in water
3, and carry out sufficient aeration.
The acidic high oxidation water that obtains is detected discovery, though Xiang Shuizhong has fed a large amount of O
3, but in the acidic high oxidation water for preparing, do not detect O basically
3The existence of composition.
The present invention is under the condition of abundant aeration, with O
3Continuously be passed in the water, unexpectedly obtained a kind of brand-new acidic high oxidation water unexpectedly, and this acidic high oxidation water has the bleaching and the bactericidal property of the acidic oxidized electric potential water of electrolytic process preparation equally.
Adopt preparation method of the present invention, obtain whole are acidic high oxidation waters, do not have the alkaline reduction water generates, simultaneously do not need electrolysis yet, greatly reduce the production cost of acidic high oxidation water.
Do not have the residual chlorine ion to exist in the acidic high oxidation water that the present invention prepares, do not have the distinctive smell of chlorion in the water, can be widely used in fields such as beauty treatment, sterilization, sterilization.
