  • Rate Constants for Reactions Between Iodine- and Chlorine-Containing Species: a Detailed Mechanism of the Chlorine Dioxide/Chlorite-Iodide Reaction†
    3708 J. Am. Chem. Soc. 1996, 118, 3708-3719 Rate Constants for Reactions between Iodine- and Chlorine-Containing Species: A Detailed Mechanism of the Chlorine Dioxide/Chlorite-Iodide Reaction† Istva´n Lengyel,‡ Jing Li, Kenneth Kustin,* and Irving R. Epstein Contribution from the Department of Chemistry and Center for Complex Systems, Brandeis UniVersity, Waltham, Massachusetts 02254-9110 ReceiVed NoVember 27, 1995X Abstract: The chlorite-iodide reaction is unusual because it is substrate-inhibited and autocatalytic. Because - analytically pure ClO2 ion is not easily prepared, it was generated in situ from the rapid reaction between ClO2 and I-. The resulting overall reaction is multiphasic, consisting of four separable parts. Sequentially, beginning with mixing, these parts are the (a) chlorine dioxide-iodide, (b) chlorine(III)-iodide, (c) chlorine(III)-iodine, and (d) hypoiodous and iodous acid disproportionation reactions. The overall reaction has been studied experimentally and by computer simulation by breaking it down into a set of kinetically active subsystems and three rapidly established - equilibria: protonations of chlorite and HOI and formation of I3 . The subsystems whose kinetics and stoichiometries were experimentally measured, remeasured, or which were previously experimentally measured include oxidation of - iodine(-1,0,+1,+3) by chlorine(0,+1,+3), oxidation of I by HIO2, and disproportionation of HOI and HIO2. The final mechanism and rate constants of the overall reaction and of its subsystems were determined by sensitivity analysis and parameter fitting of differential equation systems. Rate constants determined for simpler reactions were fixed in the more complex systems. A 13-step model with the three above-mentioned rapid equilibria fits the - -3 - -3 - - overall reaction and all of its subsystems over the range [I ]0 < 10 M, [ClO2 ]0 < 10 M, [I ]0/[ClO2 ]0 ) 3-5, pH ) 1-3.5, and 25 °C.

  • Risk Assessment Report Sodium Chlorite(The 3 Edition) (Food
    This is a provisional English translation of an excerpt from the original full report. Risk Assessment Report Sodium Chlorite(The 3rd edition) (Food Additive) Food Safety Commission of Japan (FSCJ) July 2009 Executive summary The Food Safety Commission of Japan (FSCJ) conducted a risk assessment of sodium chlorite (NaClO2) [CAS No. 7758-19-2], a food additive that is used as a bleaching agent and bacteriocide, using various test results. The test results used in the assessment are related to the repetitive dose toxicity, carcinogenicity, reproductive developmental toxicity, genotoxicity, etc. of sodium chlorite and other substances. When administered orally, sodium chlorite is assumed to convert to chlorous acid (HClO2) in gastric fluid. In - addition to chlorous acid (HClO2), substances such as chloride ion (Cl ), chlorine dioxide (ClO2), and chlorite - ion (ClO2 ) can also be produced by metabolism in the human body. Therefore, the toxicity of sodium chlorite was assessed mainly on the basis of safety data obtained for sodium chlorite, chlorite ion, and chlorine dioxide from various animal and human studies, with reference to findings related to hypochlorous acid solution and sodium hypochlorite (NaClO) as appropriate. According to the results of the safety studies for sodium chlorite and the like, the most commonly observed major effect of sodium chlorite intake was thought to be the damage to the red blood cells by oxidative stress. No carcinogenicity was observed. With regard to genotoxicity, a weak positive result was observed in a reverse mutation test using bacteria. Although a positive result was obtained in a chromosomal abnormality test using mammalian cell cultures, the result was negative as to a micronucleus test performed using a high dose.

The 18 petition before the National Organic Standards Board (NOSB) is to add ASC solution as an allowed 19 synthetic in organic livestock production (§ 205.603) for use as a disinfectant/sanitizer and topical 20 treatment (i.e., teat dip). 21 ASC solutions used as disinfectants and teat dip treatments in livestock production are analogous to those 22 used for secondary direct food processing and handling. However, the potential impacts to the 23 environment and human health resulting from ASC treatments of livestock necessitate consideration of the 24 aqueous chemistry of the parent substance and its breakdown products, and potential for toxic effects to 25 terrestrial organisms and humans potentially exposed to these substances. 26 Characterization of Petitioned Substance 27 28 Composition of the Substance: 29 The petitioned substance, acidified sodium chlorite (ASC) solution, is generated through the reaction of 30 any acid categorized as Generally Recognized as Safe (GRAS) by the FDA with an aqueous solution of 31 technical grade (~80% purity) sodium chlorite (NaClO2).
