Chlorination of aqueous solutions containing organic nitrogen: Analysis and detection with MIMS. Chii Shang, Purdue University. Abstract. In most “real-world” applications of chlorine to aqueous systems, the interactions between chlorine and organic N-compounds are of concern in terms of both disinfection efficacy and analytical by: 1.
Abstract. This paper describes the formation of organic chlorine compounds like chloroform, and chlorinated acetic acids, acetones, pyruvic acids, maleic and fumaric acids, acetonitriles and acetamides in the chloroperoxidase-mediated reaction between chloride and humic material Chemical chlorination may also occur to a small extent, because hydrogen peroxide may give rise to active by: The chemistry of hypochlorite ion in aqueous solutions is discussed in the monograph on chlorinated drinking-water (p. 50). All hypochlorite salts, as well as chlorine itself, in aqueous solution produce equilibrium mixtures of hypochlorous acid, hypochlorite ion and chlorine. In concentrated solutions, hypochlorite ion tends to disproportionate to form chlorate and chloride ions.
The aqueous chemistry of chlorine is significantly pH dependent, thus various species of this oxidant with different reactivities with micropollutants, may be present in solutions [34 Missing: book. Chlorinated Solvent Chemistry: Structures, Nomenclature and Properties; Introduction. Chlorinated solvents are a large family of organic solvents that contain chlorine atoms in their molecular structure. They were first produced in Germany in the s, and widespread use in the United States (U.S.) began after World War II.

Summary This chapter contains sections titled: Dissolution and Hydrolysis of Chlorine Dissociation of Hypochlorous Acid Chlorine Speciation in Concentrated Solutions Hypochlorite Solutions Oxidatio. The initial chlorination kinetics of several substituted dihydroxybenzenes, including chlorinated resorcinol compounds, was studied over the pH range of 2−12 at 22 °C.
For each of the resorcinol substrates, the apparent chlorination rates are a minimum in the pH range of 3−6 and a maximum at pH values between 8− A mechanism that involves the reaction of HOCl with ArX(OH)2, ArX(OH)O Cited by: To assess the estrogenic activity potentially stemming from bisphenol A (BPA) in drinking water, APCI/LC/MS and NMR were used to identify the products of its aqueous chlorination under the following conditions: μg/L bisphenol A and mg/L sodium hypochlorite (pH ) at 25 °C.

Abstract. While both aqueous bromine (HOBr/OBr −) and chlorine (HOCl/OCl −) react with natural organic matter (NOM) during water treatment, limited direct parallel comparison of bromine versus chlorine has been conducted.
Experiments with model compounds and natural waters indicated more efficient substitution reactions with bromine than chlorine. Kinetic experiments with NOM isolates with Cited by: In the case of organic compounds, second-order rate constants for chlorination vary over 10 orders of magnitude (i.e.

Chlorine added to drinking water as a disinfectant is a concern of this generation. This is because chlorine reacts with dissolved organic compounds to form polychlorinated complexes that are carcinogenic.
