At present, Titanium electrodes for disinfection of water bodies, there are chlorine gas, sodium hypochlorite, bleaching powder, chlorine dioxide, trichloroisocyanuric acid, hydrogen peroxide, ozone and other agents and methods, in addition to iodine water, high oxidized water, ultraviolet disinfection and other means.
In all disinfectants, although chlorine gas is the most economical, but chlorine gas has hidden dangers in transportation, storage, use and other aspects of safety, and there is a problem of adding measurement is difficult to accurately control;
Compared with other disinfectants, sodium hypochlorite is very advantageous. It is clear and transparent, intersoluble in water, completely solve the technical difficulties such as chlorine gas, chlorine dioxide, ozone and other gas disinfectants that are difficult to dissolve in water and not easy to accurately add, eliminate liquid chlorine, chlorine dioxide, ozone and other agents often have running, leakage, leakage, poison and other safety hazards, disinfection does not produce harmful to health and damage the environment of the side reactants. Nor is there much of the sediment that comes with using bleach. Because of these properties, sodium hypochlorite has been widely used in tap water, water, industrial circulating water, swimming pool water, hospital sewage and other water disinfection and epidemic prevention. However, because the sodium hypochlorite solution is not easy to survive, and transportation is inconvenient, sodium hypochlorite is mostly prepared and used in the way of electrolytic salt water.
Application of titanium anode
The invention of the titanium anode and its application in the sodium hypochlorite generator is undoubtedly an important breakthrough in using the technology of on-site production of sodium hypochlorite for drinking water treatment and disinfection of private and public swimming pools. Using titanium anode to produce sodium hypochlorite on site is not only safe but also environmentally friendly compared with using chlorine gas or pouring sodium hypochlorite in large quantities. Using titanium anodes to produce sodium hypochlorite avoids the use of corrosive and dangerous chemicals, such as hydrochloric acid.
The reaction principle of preparing sodium hypochlorite by electrode is electrolysis of sodium chloride dissolved in water. In the process of electrolysis, sodium hypochlorite is formed. The optimal salt concentration is 3-5 g/l. To increase salt utilization, use a diaphragm, which is commonly used in large installations and swimming pools.
The total response is expressed as follows:
NaCl + H2O → NaClO + H2↑
Electrode reaction:
Anode: 2Cl- - 2e → Cl2
Cathode: 2H+ + 2e → H2
Solution reaction: 2NaOH + Cl2 → NaCl + NaClO + H2O
Products and Services: For sodium hypochlorite generator, Mahnetto has developed special anode products which are very suitable for use, in order to achieve the effect of improving the use efficiency of salt and extending the service life of the anode. The main products are as follows:
1. Titanium anode coated with ruthenium metal oxide;
2. Iridium platinum oxide coated titanium anode.
Titanium anodes for disinfection of domestic water, food utensils and swimming pool water
In recent years, the production of micro sodium hypochlorite disinfectant generator has been increasing. The smallest generator cell volume is only 0.5L, effective chlorine content is 1.2g/L, coated titanium electrode size is 3cm in diameter, the generator is light and easy to carry, so it is very popular.
Hypochlorous acid is a small neutral molecule, which can spread to the surface of negatively charged bacteria and penetrate through the cell wall to the inside of the bacteria to perform oxidation, thus killing bacteria. The natural pond hydrogens contained 1.1×105 Escherichia coli /L, and the total number of bacteria was 2×104 /mL. After 5min of disinfection with sodium hypochlorite, the number of Escherichia coli was 100 /L, and the total number of bacteria was only 100 /mL. The sterilized pond water, tested by the health department, meets drinking water standards. Small sodium hypochlorite generator is suitable for disinfection of unclean drinking water, such as river water, well water and sugar water. It is particularly useful for field operations, field troops and areas where water supply systems are also bought.
Sodium hypochlorite can quickly kill a variety of pathogenic bacteria and viruses, such as Escherichia coli, Staphylococcus aureus, hepatitis B virus, Bacillus subtilis black mutant buds, etc. Disinfection and sterilization of household daily articles with disinfectant can effectively prevent hepatitis, typhoid, cholera, dysentery and other transmitted diseases.
Sodium hypochlorite can be used for tableware and tea set disinfection, the effect is better than high temperature disinfection;
It can be used for disinfecting, cleaning and deodorizing kitchen utensils, bathtubs and sanitary utensils.
It can be used to disinfect articles and clothes used by patients;
Can be used for infant bottles and toys disinfection;
Can be used for fruit, fish, vegetables surface disinfection;
It can be used for disinfection and sterilization of swimming pool water.
