Chlorite removal with ferrous ions
Chlorite removal with ferrous ions
****!!!!**** "the reaction between the ferrous ion and chlorite is very fast (5–15 s) over a range of pH 6.5–8.0; in this condition a ferrous ion dose of 3.31 mg Fe/mg ClO2 completely reduced chlorite to chloride, producing minimal residual soluble iron. For pH higher than 8.0–8.5, chlorite removal is lower due to the natural transformation of the ferrou ions to ferric hydroxide. Within these pH values, chlorite can be removed completely with ferrous ion concentrations higher than the stoichiometric value. Moreover, the application of ferrous salts for chlorite removal during the coagulation process enhances the performance of the coagulation and flocculation treatment"

ANTIMICROBIAL EFFECT OF SLOW RELEASE CHLORINE DIOXIDE DISINFECTANT, IN COMPARISON WITH SODIUM DICHLOROISOCYANURATE
ANTIMICROBIAL EFFECT OF SLOW RELEASE CHLORINE DIOXIDE DISINFECTANT, IN COMPARISON WITH SODIUM DICHLOROISOCYANURATE
"This study assessed the antimicrobial properties of Aseptrol® (48 ppm and 24 ppm)" "Both disinfectants killed more susceptible bacteria, such as Staphylococcus aureus, Pseudomonas. aeruginosa and Streptococcus mutans within 30 seconds and proved to be fungicidal by killing Candida albicans within 30 seconds.Aseptrol® and Presept® killed less susceptible mycobacteria such as Mycobacterium tuberculosis, Mycobacterium avium subsp. avium and blood borne organism Hepatitis B virus within 30 seconds. Highly resistant B. subtilis spores were killed in 2 and 2.5 minutes by Aseptrol® and Presept® respectively." "Although manufacturers recommend that the disinfectant solutions should be prepared daily, when the shelf-life of prepared solutions stored in screw cap bottles was studied, the results showed that Aseptrol® can be effectively used for 27 day" "nosocomial infections"

"The inactivation mechanisms were explored by analyzing the leakage of intracellular substances, the increase in extracellular adenosine triphosphate (ATP), deoxyribonucleic acid (DNA), and proteins as well as the changes in spore morphology. The kinetics of inactivation by chlorine dioxide fitted the Chick-Watson model, and different fungal species showed different resistance to chlorine dioxide inactivation, which was in the following order: Cladosporium sp.>Trichoderma sp. >Penicillium sp., which are much more resistant than Escherichia coli." "Regarding the three genera of fungal spores used in this study, chlorine dioxide was more effective at inactivation of fungal spores than chlorine." "The effect of disinfectant concentration and temperature was positive, and the impact of pH levels (6.0 and 7.0) was insignificant, whereas the influence of water matrices on the inactivation efficiency was negative. The increased concentration of characteristic extracellular substances and changes of spore morphology were observed after inactivation with chlorine dioxide and were due to cell wall and cell membrane damage in fungal spores, causing the leakage of intracellular substances and death of a fungal spore."

Activity of Chlorine Dioxide in a Solution of Ions and pH Against Thielaviopsis basicola and Fusarium oxysporum

****!!!!*** "ule type that potentially had low sensitivity to ClO2. The information generated from this research indicates whether a narrow or wide range in rate of ClO2 is needed for efficacy against different fungal propagules as a result of the interactions of water properties (e.g., pH and water hardness) that vary with the source (e.g., ponds, wells, municipal water, and recirculating systems), in combination with the presence of nutrient leachates that collect in catchment ponds and ebb-and-flow systems" " a high reduction in viable propagules resulted when conidia or sporangiospores of Botrytis cinerea, Penicillium expansum, Mucor piriformis, and Cryptosporiopsis perennans... These papers demonstrated that concentration of ClO2 varies with time, with an equal mortality of propagules obtained at lower concentrations of ClO2 by lengthening the duration of exposure. " "A higher concentration of ClO2 was required at pH 8 than at pH 5 to achieve a lethal dose resulting in 50% mortality of spores (LD50). The addition of the divalent metal ion solution required an increase in ClO2 concentration to maintain a LD50. When combined with the nitrogen and hard water solution, the divalent metal ion solution placed a higher demand on ClO2 at pH 5 and a lower demand on ClO2 at pH 8,"

***!!!!*** {Includes table of pathogen effectiveness levels} "Chlorite is the major inorganic by-product of the reaction of chlorine dioxide in water. Usually, the amount of chlorite formed will be 40-60% of the amount of chlorine dioxide which has reacted. " "Chlorine dioxide systems: acid chlorite and electrochemical generators "Typical chlorite yield for an acid-chlorite generator varies between 65-68%. Overall conversion efficiency is much lower than this as much of the acid remains unreacted." "Chlorine Dioxide ClO2 will inactivate pathogenic micro-organisms at the same rate between pH 5 and 9. This makes it ideal for disinfection of potable water and process water where the pH is up around 8.0."

Chlorine Dioxide (CLO2) As a Non-Toxic Antimicrobial Agent for Virus, Bacteria and Yeast (Candida Albicans)
Chlorine Dioxide (CLO2) As a Non-Toxic Antimicrobial Agent for Virus, Bacteria and Yeast (Candida Albicans)
{A number of statements in this document need verification. Author has non-traditional background.} "The use of a family of chemical agents, releasing active species of oxygen, effective against infectious microorganisms and viruses is described with emphasis on Chlorine Dioxide (CLO2), one of the oxides of chlorine. " "Explanation of the biochemical mechanisms of acid of CLO2 as an anti-microbial agent, is presented. Particular attention is given to Candida albicans, cytomegalovirus, polio virus, Herpes I and II, HTLV-III and Pseudomonas responding to the clinical application of CLO2. It is implied that these biochemical mechanisms are so fundamental that the development of resistant strains of bacteria and/or yeast would not occur with other anti-infectious agents. Limited lists of health abnormalities that respond to CLO2 are discussed."
