In other words, Redox is a compound word of reduction and oxidation and it uses the redox principle that occurs naturally between metal alloy and water.
In particular, the
Here, copper (Cu) is an essential nutrient for mammals including humans, but is mostly ingested from food, but in other organisms such as microorganisms, the demand is very low at 1 to 10 levels. Will be removed.
Therefore, when the redox reaction energy is increased, the sterilization effect of various fungi, the sterilization effect of algae, moss and mold, and the effect of preventing the adhesion of scales will be described in detail with reference to FIG. 5.
The principle of sterilization by redox reaction is as follows.
Cu / Zn 0- > Cu +2 / Zn +2 + 2e - Reduction
H 2 O + 2e - -> OH - + .H oxidation
H 2 O + .H-> .OH + H 2
Therefore, the
That is, in the process of redox reaction, the metal emits electrons (e-) through oxidation. First, the electrons act on cells of bacteria such as bacteria to hemolyze the cell wall to kill the bacteria. Secondly, the released electrons interact with seawater to produce hydrogen radicals (.H), and hydrogen radicals react with seawater to produce hydroxyl radicals (.OH). It reaches about 800 times (Cl). Third, a hydroxyl group (OH-) is produced in the reaction process, and the pH increases due to the hydroxyl group. When the pH is 9.5 or more, it becomes an environmental condition that various bacteria are difficult to inhabit, so that effective sterilization is possible because it makes strong sterilization and the culture environment of bacteria difficult during the redox reaction.
