When the TwinOxide solution is applied, the chlorine dioxide molecule kills the full spectrum of bacteria, algae, fungi, spores, protozoan, yeast, methanogens, viruses, mold and biofilm by its great oxidizing capacity. It is difficult to prove the mutagenity of chlorine dioxide and chlorine dioxide byproducts, because the substances are biocides. Viruses are eliminated in a different way; chlorine dioxide reacts with peptone, a water-soluble substance that originates from hydrolisis of proteins to amino acids. At low pH, chlorine dioxide is reduced to chloride ions (Cl- ). Figure 1: sir Humphrey Day discovered chlorine dioxide in 1814. Sodium chlorate (NaClO3) was used instead of potassium chlorate. It does oxidize nitrite (N02) to nitrate (NO3). Table 3: the availability of chlorine per mol weight, Does chlorine dioxide oxidize in the same way as chlorine? Chlorine dioxide as an oxidizer As an oxidizer chlorine dioxide is very selective. (570 doses of foam/bottle) Downloads All. It is also active against the formation of bio film in the distribution network. Chlorine dioxide is more effective for the removal of iron and manganese than chlorine, especially when these are found in complex substances. What are the disinfection applications of chlorine dioxide? Chlorine dioxide is approximately 10 times more soluble in water than chlorine. Chlorine dioxide remains gaseous in solution. He produced the gas by pouring sulphuric acid (H2SO4) on potassium chlorate (KClO3). Instructions of Chlorine Tablets for Disinfection: Add 1 liter of water to the plastic cup, add disinfection tablets, it will automatically dissolve in 2-3 minutes, stir, and let stand for 5 minutes to become 1 liter of yellow-green transparent chlorine dioxide solution. The amount of chlorine dioxide that is dosed depends upon the contact time, the pH, the temperature and the amount of pollution that is present in the water. Chlorine dioxide (ClO2) is a synthetic, green-yellowish gas with a chlorine-like, irritating odor. Safety Data Sheets.
