TL;DR: It is concluded that NaClO 3 and KClO3 show no promoting effect in rat renal carcinogenesis under the conditions of this study.
Abstract: Sodium chlorate (NaClO3) and potassium chlorate (KClO3), which are byproducts of water disinfection with chlorine dioxide (ClO2), were tested for potential promoting effect in two-stage rat renal c...

TL;DR: In this article, a process for production of chlorine dioxide and chlorine by reacting sodium chlorate with chloride ions and sulfuric acid where the chlorine ions partly are obtained from hydrochloric acid is described.
Abstract: A process for production of chlorine dioxide and chlorine by reacting sodium chlorate with chloride ions and sulfuric acid where the chlorine ions partly are obtained from hydrochloric acid is described. In the process chlorine obtained as a by-product is reacted with sulfur dioxide in a reactor equipped with a condenser. The heat of reaction is removed by keeping the reactor at or above the boiling point of the reaction medium and the vapors are condensed in the condenser and brought back to the reactor. The obtained mixed acid comprising sulfuric acid and hydrochloric acid is returned to the chlorine dioxide reactor.

TL;DR: In the production of chlorine dioxide from concentrated solutions of sodium chlorate and hydrogen chloride, plugging of the generator is prevented by initially mixing the solutions under vigorous agitation conditions as discussed by the authors.

TL;DR: In this article, the influence of specific factors in chlorate electrilysis on the corrosion behavior of ROTA was studied based on neutron activation of the test specimens followed by corrosion tests.
Abstract: The authors studied the influence of specific factors in chlorate electrilysis on the corrosion behavior of ROTA. The technique used in the investigation was based on neutron activation of the test specimens followed by corrosion tests. Figures show the dependence rate of ruthenium dissolution on the sodium chloride production during production of chlorate by electrolysis with ROTA, and dependence of the rate of ruthenium dissolution and of the rate of oxygen evolution during polarization of ROTA. Over the entire range of ROTA potentials studied the process of oxygen evolution conforms to the Tafel relationship. The rate of ruthenium dissolution in chlorate solution rises by more than 4 orders of magnitude with increase of the ROTA potential.

TL;DR: Sodium chlorate is prepared with increased Faraday yield using electrolysis in a tank equipped with metal electrodes coated with electrochemical activating agents, such as platinum-iridium or ruthenium oxide, in the presence of hydrochloric acid for pH control as mentioned in this paper.
Abstract: Sodium chlorate is prepared with increased Faraday yield using electrolysis in a tank equipped with metal electrodes coated with electrochemical activating agents, such as platinum-iridium or ruthenium oxide, in the presence of hydrochloric acid for pH control Phosphoric acid, in the required amount per 1 ton NaClO3 is 0.85-1.7 kg, is added into the electrolyte to increase the Faraday yield due to reduction of oxygen-gas generation.
