Sodium chlorate oxygen generation for fuel cell power systems
… we experimentally investigated the use of sodium chlorate as an oxygen storage medium for use in underwater fuel cell power systems. Research into improving hydrogen storage systems is the primary concern when designing fuel cell systems with access to atmospheric oxygen. However, in an underwater …

The design of a non-diaphragm calcium chlorate cell
… Process. Data was obtained to show the effect on chlorate formation of the variables; temperature, concentration of electrolyte, and current concentration. In all the experimental runs, observations were made of the weight of calcium scale formed on the cathode surface end of the anode …

Comparison of ion chromatography and flow injection analysis methods for monitoring chlorite and chlorate ions in drinking water
… level measurement of chlorite ion (CI0₂-) and chlorate ion (CI0₃-). This research investigated analysis of CI0₂- and CI0₃-; in drinking water by flow injection analysis with iodometric detection (FIA) and ion chromatography with conductivity detection (IC). Both the FIA and IC methods were …

Nitrate carrier induction and characterization in maize root plasma membrane using chlorate-36 as a radiotracer analog for nitrate
Previous studies with intact maize plants have shown an apparent induction of nitrate uptake capacity when plants are transferred to a nitrate containing nutrient solution. Whether this phenomenon reflects a change in nitrate carrier activity at the membrane level or an effect of nitrate metabolism …

Studies on the Mechanism of the Chlorination Reactions Catalyzed by Chloroperoxidase and by Horseradish Peroxidase With Chlorite
… of chlorite-forming chloride, chlorine dioxide, chlorate, and oxygen as products. Chloroperoxidase also catalyzes the decomposition of chlorine dioxide. Chloride, chlorate, and oxygen are the products of the decomposition of chlorine dioxide. The optimum pH for the enzymic decomposition of both …

The characterisation of Manganese (IV) compounds and the study of the thermal decomposition of Potassium Chlorate alone and with Mn(IV) and other oxides and salts
… reaction between these compounds and potassium chlorate. A literature search revealed major contradictions in the reported conditions under which potassium chlorate undergoes thermal decomposition as result of which it was decided to study the decomposition of potassium chlorate alone and in the …

Chlorine dioxide and by-products in water distribution systems
… is associated with its byproducts chlorite and chlorate. Chlorine dioxide, chlorine, chlorite and chlorate were sampled in four distribution systems where chlorine dioxide is used for disinfection purposes: Charleston, WV, Columbus, GA, New Castle, PA, and Skagit, WA. The fate of chlorine …

Chlorine dioxide by-products in drinking water and their control by powdered activated carbon
… dioxide (CI02), chlorine, chlorite (CIO2), and chlorate (CI03) were evaluated following pretreatment of raw water by CI02 at water treatment plants in New Castle, Pennsylvania; Charleston, West Virginia; Skagit, Washington; and Columbus, Georgia. Chlorite and chlorate concentrations were …

Microbial Oxidation of Arsenite in Anoxic Environments: Impacts on Arsenic Mobility
… to distribute in the subsurface. Nitrate or chlorate can be considered as alternative oxidants with advantages over elemental oxygen due to their high aqueous solubility and lower chemical reactivity which together enable them to be better dispersed in the saturated subsurface.The objective …

Nitric oxide-induced DNA recombination & glycosaminoglycan mediated differentiation in stem cells
… ablation of the HSGAG-biosynthetic machinery by chlorate treatment, or by the enzymatic degradation of the HSGAGs. Exogenous addition of heparin to chlorate-treated cells partially restored differentiation into endothelial cells. These effects were mirrored in phospho-ERK levels, suggesting the …

Active hyperspectral imaging of chemicals on surfaces
… on surfaces was demonstrated using potassium chlorate particles on car panels at distances of 5 m, 10 m, and 20 m. Using the Adaptive Cosine Estimation (ACE) algorithm which compares the observed reflectance spectra to a reference spectrum, potassium chlorate fingerprints are easily visible at …

The Effect of Predisinfection with Chlorine Dioxide on the Formation of Haloacetic Acids and Trihalomethanes in a Drinking Water Supply
… two inorganic byproducts of ClO2, chlorite and chlorate, were also measured following jar tests. Chlorite concentrations increased with an increased ClO2 dose, but remained below 1.0 mg/L. Chlorate was formed in all jar-test samples.

Removal of chlorite by reaction with ferrous iron
… residual concentrations of chlorite and chlorate have resulted in limitations on applied chlorine dioxide dosages. This study describes the use of ferrous iron as a possible reducing agent for the elimination of residual chlorite from drinking water.

Evaluation of the use of ferrous iron for chlorite removal under alkaline pH conditions
… to the disinfection-by-products of chlorite and chlorate. The main objective of this project was to study the removal of chlorite by reaction with ferrous iron under elevated pH conditions. The stoichiometry of the reaction was evaluated under the following conditions: solution pH of 6.0 to 10.0, …

Evaluation of different powdered activated carbons in the control of chlorite ion
… and in the production of chloride ions (Cl⁻) and chlorate ions (ClO₃⁻) during that removal. All screenings were conducted in reagent water, at pH 7.0 ± 0.2 pH units, with a standard concentration of 20 mg/liter of powdered activated carbon (PAC) added in each case, and with the process and samples …

Characterization of Insulin-like Growth Factor Binding Protein-3 (IGFBP-3) interaction with the Bovine Aortic Endothelial (BAE) cell surface: Examination of the Role of Heparan Sulfate Proteoglycans (HSPG)
… of the cell surface HSPGs with 75 mM sodium chlorate did not affect IGFBP-3 binding. Further, there have been reports of inhibition of IGFBP-3 binding by heparin in the media. Hence, the most probable interaction of HSPG with IGFBP-3 occurs in the extracellular region, with soluble HSPGs …
