Chemical & Biological Dynamics

Periodic table, in chemistry, the organized array of all the chemical elements in order of increasing atomic number. When the elements are thus arranged, there is a recurring pattern called the ‘periodic law’ in their properties, in which elements in the same column (group) have similar properties.

Radioactive decay is the emission of energy in the form of ionizing radiation. Example decay chains illustrate how radioactive atoms can go through many transformations as they become stable and no longer radioactive.

"Both CI02 and CI02- are readily decomposed by sunlight and fluorescent lights. This can lead to significant losses during water treatment. The characteristics of the water play an important role in the nature of products resulting from light-initiated reactions. Significant levels of CIO)-, BrOf, and bromo-form can be produced. The bromide ion was found to play a particularly important role in THM formation and initiating light reactions that accellerated the decomposition of ClO2 in the dark."

****!!!!**** "ClO2 reacts quickly with the amino acids,Cysteine and Methionine (two Sulphur-containing amino acids), with Tyrosine and Tryptophan (two aromatic amino acids) and with two inorganic ions: Iron (Fe2+) and Manganese (Mn2+).A study into the antiviral effect of chlorine dioxide against Influenza Virus revealed that ClO2performed an oxidative modification of Tyrosine residue and Tryptophan residues in the viral capsid surface proteins, hemagglutinin (HA) and neuraminidase. It also reacts with free fatty acids found within the virus.Additional research on chlorine dioxide’s efficacy towards Poliovirus shows that treatment results in reduced incorporation of Uridine (one of the four base units which comprise RNA). This results in the viral genome being unable to act as template for RNA synthesis therefore resulting in the virus being unable to replicate. Chlorine dioxide is also able to disrupt Sulphurbonding interactions within the viral capsid protein which leads to changes in the virus shape resulting in a loss of pathogenic functionality. In conclusion, the mechanism of Tristel’sproprietary chlorine dioxide chemistryin destroying Coronaviridaeis expected to beacombination of oxidative modification of amino acids and fatty acids, RNA synthesis disruption and viral capsid modification. All of these in combination lead to the lysing (destruction) of the virus."

"Chlorine dioxide foam activating agents (acid solutions combined with surfactants, scale sequestrants, lubricants, detergent salts, and/or corrosion inhibitors)" **********"Sodium Chlorite is related to available chlorine dioxide by the ratio of molecular weights (67.45/90.45). For example: 87.8 ppm NaClO2 = 87.8x (67.45/90.45) ppm ClO2
