Medicine, 2003
Chlorine is a greenish-yellow, corrosive gas with a distinctive odour. It is a strong oxidizing agent and highly soluble in water. It is easily absorbed through mucous membranes. Following exposure to chlorine the clinical symptoms appear instantly on exposure and may consist of nasal discharge, lacrimation, pain in the upper airways, dyspnoea ...

Chlorine and chlorine chemistry
Environmental Progress, 1998AbstractThe important technical and economic roles played by chlorine chemistry in the United States and, to a lesser extent, the world as a whole are reviewed.

Disinfection with Chlorine and Chlorine Dioxide
Journal of Environmental Engineering, 1983Disinfection with chlorine dioxide was compared to disinfection with chlorine in wastewater from three treatment sequences: (1) Conventional activated-sludge treatment; (2) activated-sludge/nitrification; and (3) activated-sludge/nitrification/filtration treatment.

Super‐Chlorination and De‐Chlorination
Journal AWWA, 1941IS indeed strange that so many operators fail to appreciate the vast increase in plant efficiency and the reduction in operating problems which result from a conscientious and thorough study of the all-important problem of preparing a water for filtration.

Chlorine Hexoxide and Chlorine Trioxide
Nature, 1933A RED oily liquid was detected by Bowen1 in a study of the photochemistry of chlorine dioxide. This substance was isolated by Bodenstein, Harteck and Padelt2 and was found by them to contain three atoms of oxygen to one of chlorine. Its molecular weight when dissolved in carbon tetrachloride was found to be 153–156 and it was called chlorine hexoxide ...

International Archives of Occupational and Environmental Health, 1996
Environmental groups have called for a phaseout of the use of chlorine in industrial chemistry on the grounds that such use inevitably leads to the production of persistent, bioaccumulative toxins. This policy prescription is based on an application of the Precautionary Principle which holds that industry should demonstrate that its products and ...

Water Research, 2012
Most studies on membrane chlorination have been investigated in an unpressurized chlorination mode, even if the polyamide membrane was continuously exposed to chlorine under high operating pressure in real water/wastewater treatment plants. In this study, performance changes due to polyamide membrane chlorination were investigated in both pressurized ...

Breakpoint Chlorination—the Chemistry of Chlorine
Opflow, 1982This article is a continuation of “Chlorine‐‐‘Special Agent’ for Disinfecting Water” by Ralph Leidholdt (OpFlow September 1982). In this selection, the author discusses the chemical reactions that occur when chlorine gas, calcium hypochlorite, or sodium hypochlorite is added to water for disinfection purposes.

Reactions of Aqueous Chlorine and Chlorine Dioxide with Lipids: Chlorine Incorporation
Journal of Food Science, 1982ABSTRACTVarious lipids were reacted with HO36Cl and 36ClO2 in an aqueous medium, and the extent of incorporation of 36Cl into the lipids was determined. Cl incorporation into lipids treated with HOCl was greater than lipids treated with ClO2. Free fatty acids incorporated more Cl than their corresponding esters.

Analysis of Mixtures of Chlorine and Chlorine Dioxide [PDF]
Analytical Letters, 1981 Abstract The concentrations of chlorine and chlorine dioxide in a gas stream may be determined by passing a known quantity of gas into an acidic potassium iodide solution with subsequent analysis of that solution for iodine by thiosulfate titration and chloride by ion chromatography.
