"There has been a trend toward the use of microorganisms as the biomaterial for removing dyes and metals from wastewater. However, native microorganism cells have low mechanical stability, which limit their further application in industries. In this study, chlorine dioxide (ClO2), a high-efficiency, low-toxicity, and environmentally benign disinfectant, was used for microorganism surface modification to enhance the mechanical stability and metal ion adsorption of the cell. ClO2 can either modify cell walls to improve their metal adsorption capacity or modify cell membranes to improve their mechanical stability... ClO2 treatment could deter cell membranes from forming vesicles in sodium hydroxide (NaOH) aqueous solution, and ... ClO2 treatment could alter the erythrocyte membrane proteins which might also contribute to improving the cell stability. The experimental results on Bacillus sp., Pseudomonas aeruginosa, and Mucor rouxii show that ClO2 treatment may increase, or at least not reduce, the ability of microbial cells to adsorb heavy metals, but it can significantly improve the resistance of these cells to NaOH cleavage. It seems ClO2 is a promising auxiliary for biosorption of heavy-metal ions."

Chlorine dioxide (ClO2) is a highly effective disinfectant for food and potable water treatment. Till now, the action mode of ClO2 is still unclear. ClO2, can denature proteins by oxidizing tyrosine, tryptophan, and cysteine. We reviewed the pathways by which ClO02 reacts with important bio-molecules, as well as the primary target sites at individual cellular level of ClO2-induced biocidal effects.

Trihalomethane (THM) formation was determined by gas chromatography in water disinfected with chlorine dioxide (ClO2) only or ClO2 combined with chlorine (Cl2), to lay a basis for water disinfected with ClO2. Results showed no THM was produced in water disinfected with ClO2 only if without existence …

The present invention relates to a dosing system comprising a housing enclosing : a first closed container adapted to contain a solution of a first oxychlorine compound, the first closed container including a first conduit and a second conduit; and a second closed container adapted to contain a neutralizer, the second closed container in fluid communication with the first closed container via the second conduit, wherein the first conduit is adapted to convey the solution of the first oxychlorine compound or part thereof to mix with a fluid to obtain and dispense a cleaning fluid, and wherei...

The present invention relates to an aqueous composition comprising chlorine dioxide having a concentration of at least 4 g of chlorine dioxide per liter, to a method for producing such aqueous composition and to a kit comprising concentrated solutions of chlorite salt, and bisuiphate and persulphate salt. The composition according to the invention can advantageously be used in oil and gas industry, for the treatment of industrial waste water, for the treatment of household waste water, for the treatment of drinking water, for controlling odours, and/or for disinfection of food, goods, anima...

The photochemistry of condensed films of OClO was examined with photofragment spectroscopy. Photolysis of multilayers of OClO on a polycrystalline Pt surface with 355 nm light yields predominantly atomic O, O2, atomic Cl, and ClO photofragments. We have measured the quantum yield for the Cl product channel to be 0.8±0.1, which is approximately 800 times higher than reported values for the non‐resonant gas‐phase photolysis of OClO. This result may have implications for stratospheric ozone chemistry.

"Theformation of chlorine dioxide (ClO2), which is known to reactwith DPD,22is also excluded on the basis of the observationthat sparging with argon, which will remove ClO2if present, didnot decrease the observed DPD•+absorbance in both thepresence and absence of glycine (Figure S5of the SupportingInformation)."

Equine fibroblasts and Staphylococcus aureus were exposed for 30 minutes to six dilutions of chlorhexidine gluconate, a chlorous acid‐chlorine dioxide irrigation solution, a chlorous acid‐chlorine di...

"The data showed that the residual of chlorine dioxide could stood more active than residual of chlorine in the aqueous environment significantly."

What is chlorine dioxide? Chlorine dioxide (ClO2) is a highly effective, eco-friendly micro biocide that carries the US EPA, FDA and UK Government approvals for many of its uses. It is a selective oxidant that eliminates many pathogenic organisms including Legionella, Listeria, Salmonella, amoeba cysts, Giardia cysts, E. Coli, and Cryptosporidium. Importantly, CIO2 also destroys [...]

SMT’s ultra-pure ClO2 minimizes downtown for diagnostic equipment such as chemistry, immunoassay & hematology analyzers by decontaminating fluidic lines.

***!!!!*** {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." "ClO2 is approximately 5 times more soluble than chlorine and 50 times more soluble than ozone." "Chlorine Dioxide Reaction with Inorganic Compounds--Ammonia Nitrogen... Iron... Manganese..."

{ Fumigation against Bacillus anthracis} "Results from the 750 ppmv ClO2 fumigation suggest that 750 ppmv was more damaging to Category 4 materials than the 3000 ppmv ClO2 fumigation. Although both fumigation concentrations resulted in severe physical damage to the computers by promoting rusting and corrosion, only the computers exposed to 750 ppmv ClO2 experienced unrecoverable failures. It is not readily understood why the lower concentration (same RH) fumigation was more damaging; however, the same sample size and difference in computer batches cannot be ruled out as confounding parameters." "fumigation with ClO2 produced large amounts of dust inside the computers... an acrid smell (attributed to hydrogen chloride)... Vacuuming of the visible dust not only served to remove the majority of this probable health hazard and prevent the dust from being spread... also may have assisted in keeping all computers almost fully operational after an entire calendar year. "

"Chlorine dioxide generated by acidifying sodium chlorite solutions (sometimes called stabilised chlorine dioxide) can also be highly corrosive due to the presence of excess acid. Pure chlorine dioxide whether present as a gas or as a solution in water is not corrosive."
