Six major functions of chlorine dioxide

I have talked a lot about the usage of chlorine dioxide and so on. Today I will show you the return of chlorine dioxide to its original source. From the nature of chlorine dioxide, let’s see what uses chlorine dioxide itself has: Used as oxidant, deodorant, biocide, preservative, bleaching agent, etc.
  1. Algae killing effect of chlorine dioxide
Chlorine dioxide controls algae mainly because it has a certain affinity for the benzene ring, which can make the benzene ring change without odor. The pyrrole in chlorophyll is very similar to the benzene ring, and chlorine dioxide can also act on the pyrrole ring. In this way, chlorine dioxide oxidizes chlorophyll, and plant metabolism is terminated, which interrupts the synthesis of protein. The result of this reaction is that the damage to plants is that the protoplasm is dehydrated to bring about hypertonic shrinkage (plasma wall separation), which is an irreversible process that leads to the death of algae.

  1. The role of chlorine dioxide in killing viruses and germs
Chlorine dioxide is a broad-spectrum disinfectant. Chlorine dioxide can kill Escherichia coli, bacterial spores, heterotrophic bacteria, sulfate reducing bacteria and fungi in the water distribution network in a wide range of pH values. Its killing effect is related to temperature T and is a function of temperature (1/T). This advantage makes up for the disadvantage of lowering the solubility of chlorine dioxide in water due to temperature rise. Chlorine dioxide has a stronger killing effect on spores than chlorine, and has a better killing effect on wild bacteria, actinomycetes, and sporophytes in the water. Use in a variety of scenarios to protect the health of you and your family anytime, anywhere
  1. The deodorizing effect of chlorine dioxide
ClO2 can react with sulfides, and the odor is often caused by sulfides (such as ammonium sulfide, hydrogen sulfide, dimethyl sulfide, etc.). After ClO2 gas comes into contact with odorous sulfur-containing pollutants, it rapidly undergoes oxidation reaction and transforms into other substances to remove the odor. Therefore, making ClO2 a stable solution can be used in refrigerators, indoor air deodorization, sterilization, etc., and it is also used in oral medicine to eliminate bad breath and smoke odor.

The preservation of chlorine dioxide According to related reports, poultry meat treated with a chlorine dioxide solution with a concentration of 40-60 mg/L for five minutes can effectively control microbial contamination of the poultry body, and the storage period can be effectively prolonged below 5°C. The marine fishing industry uses chlorine dioxide aqueous solution to treat the captured prawns, first soak them in 40mg/L chlorine dioxide aqueous solution for 10-20 minutes, and then use 20mg/L chlorine dioxide ice cubes to keep them fresh. The prawns will not turn black. While disinfecting and sterilizing with chlorine dioxide, it will not denature biological protein and lose the existing nutrients and value, and has no effect on aquatic cells. preservation of chlorine dioxide
  1. Oxidation of chlorine dioxide
1) Chlorine dioxide oxidation of phenol The oxidation removal effect of chlorine dioxide on phenol increases with the increase of chlorine dioxide dosage (its removal rate of phenol is obviously better than that of liquid chlorine). When the concentration of phenol in the source water is 2.0 mg/L and 5 mg/L chlorine dioxide is added, the removal rate of phenol is generally greater than 85%. With the traditional chlorine disinfection, the amount of chlorophenol increases with the increase of the liquid chlorine dosage, but when chlorine dioxide is added, chlorophenol is basically not formed. 2). Chlorine Dioxide Oxidation of Organic Matter The most distinctive feature of chlorine dioxide’s oxidative degradation of organic matter is that it does not generate organic chlorine. Chlorine dioxide can control the formation of trihalomethane (THM) and reduce the production of total organic halogens. As we all know, the precursors of trihalomethane usually fall into the following three categories: one is natural macromolecular organics, such as humic acid, fulvic acid, etc.; the other is small molecular organics, such as acid compounds, aniline, and benzoquinone , Amino acids and other organic substances; the third category is algae and metabolites.
  1. The bleaching and decolorization of chlorine dioxide
Chlorine dioxide, as an oxidant with strong oxidizing properties and rarely produced by organic halogens during the oxidation process, has been widely used in industries such as papermaking and bleaching in the pulp industry. Using ClO2 as a bleaching agent, compared with other bleaching powder and chlorine, ClO2 can improve the whiteness, prevent the fiber strength from being reduced, simplify the production process, and avoid the hazards of generating a large number of carcinogens by generating free chlorine. ClO2 can also kill microorganisms in the bleaching process, effectively disperse the mucus and inorganic deposits in the pulp, thereby eliminating the formation of solid lumps in the pulp and improving the quality of the paper. Using the oxidation effect of chlorine dioxide, under proper conditions, ClO2 has a good decolorization effect. For example, ClO2 Jiangsu Tianlun Dyeing and Weaving Industrial Company and Jingjiang No. 3 Textile Factory used the coagulation/ClO2 combined method to treat printing and dyeing wastewater. The pH of the treated water dropped from 11-14 to 7, and 12 to 7; 1000 dropped to 50, 600 dropped to 5, the removal rate reached 95% and 99.2%. Other indicators such as COD, BOD5, SS, S2- are all reduced and meet the national industry emission standards.
