What is Chlorine dioxide?

Chlorine Dioxide is a small, volatile and very strong molecule consisting of 1 Chlorine atom and 2 oxygen atoms. Abbreviated to ClO2, chlorine dioxide exists as a free radical in dilute solutions • It has a molecular weight of 67.45. • It is a gas at normal temperatures and pressures. • It has a melting point of -59oC. • It has a boiling point of 11oC. • It is yellowish/green and has an odour similar to that of Chlorine. • It is denser than air and is water soluble at standard temperatures and pressures up to 2500ppm. • It is explosive in air at concentrations > 10% • It is prohibited from road and sea transport in its "free" form, and is normally generated at the point of application using 2 precursor chemicals. • It will decompose in the presence of UV, high temperatures, and high alkalinity (>pH12)

What makes chlorine dioxide different to Chlorine?

 We should not be misled by the fact that chlorine and chlorine dioxide share a word in common. The chemistries of the two compounds are completely different.Zydox

Chlorine dioxide is generally accepted to be, more powerful, easier to use, and more environmentally friendly than equivalent chlorine treatments. It is a more expensive treatment, but its superior environmental performance meants that it is rapidly replacing chlorine in a number of applications.

Chlorine and chlorine dioxide are both oxidising agents (electron receivers). However, chlorine has the capacity to take in two electrons, whereas chlorine dioxide can absorb five. This means that, mole for mole, ClO2 is 2.5 times more effective than chlorine.

If not greater importance is the fact that chlorine dioxide will not react with many organic compounds, and as a result ClO2 does not produce environmentally dangerous chlorinated organics. For example; aromatic compounds have carbon atoms arranged in rings and they may have other atoms, such as chlorine, attached to these rings, to form a chlorinated aromatic - a highly toxic compound that persists in the environment long after it is produced.  

Chlorine dioxide's behaviour as an oxidising agent is quite dissimilar. Instead of combining with the aromatic rings, chlorine dioxide breaks these rings apart. In addition, as the use of chlorine dioxide increases, the generation of chlorinated organics falls dramatically. 

How does Chlorine Dioxide react with bacteria and other biological material you disinfect?

When bacteria are eliminated, the cell wall is penetrated by chlorine dioxide. Organic substances within cells and on the surface of cell membranes react with chlorine dioxide, causing cell metabolism to be disrupted. Chlorine dioxide also reacts directly with amino acids and the RNA in the cell. This reaction is not dependent on reaction time or concentration. Unlike non-oxidizing disinfectants, chlorine dioxide kills microorganisms even when they are inactive. Microorganisms are unable to build up resistance to chlorine dioxide. in practical terms however, few bacteria live alone, and they are most often found in water and on surfaces in the form of a "biofilm" which is a close association of many millions of bacteria. Many biocides have particular problems in penetrating this biofilm, due to the polysaccharide "glue" that is secreted by the bacteria to hold the biofilm together. Unlike most biocides, chlorine dioxide can effectively penetrate biofilm to provide complete protection. Find out more here Chlorine dioxide kills viruses by preventing protein formation. ClO2 reacts with peptone, a water-soluble substance that originates from hydrolisis of proteins to amino acids. Chlorine dioxide is one of a number of disinfectants that are effective against Giardia Lambia and Cryptosporidium oocysts, which cause diseases suchs as cryptosporidiosis in public drinking water supplies. A number of public water works are now utilising chlorine dioxide generation systems alongside UV systems in order to provide complete protection from Cryptosporidium.
