0000041569 00000 n This study investigates the adsorption behaviors of chlorate and chlorite by MIEX resin, and determines the optimal conditions for the removal rate by utilizing response surface methodology. Quantitative determination of chloride, chlorite, and chlorate ions in a mixture by successive potentiometric titrations. Her interest areas for writing and research include Biochemistry and Environmental Chemistry. Chlorite and chlorate have been shown to effect red blood cells in animal studies, but similar results did not appear in the highest doses tested on humans (36 micrograms per kilogram of body weight). Chlorite, chlorate and perchlorate presented a good separation effect. El Paso is able to feed much higher levels of chlorine dioxide because ferrous chloride is used to convert the chlorite to harmless chloride while co… Chlorate Been found there form chlorite that electron % of chlorine gas ( it undergoes both oxidation and reactions., followed by addition of Potassium chloride an electron – Outline of common Features 4 dioxide added to drinking will. endstream endobj 209 0 obj <> endobj 210 0 obj <>/Encoding<>>>>> endobj 211 0 obj <> endobj 212 0 obj <>/Font<>/ProcSet[/PDF/Text]/Properties<>/ExtGState<>>> endobj 213 0 obj [/ICCBased 234 0 R] endobj 214 0 obj [/DeviceN[/Cyan/Magenta/Yellow/Black]213 0 R 244 0 R] endobj 215 0 obj <> endobj 216 0 obj <>stream 0000054036 00000 n DIN 19643) as a parameter that should be tested. Sodium chlorite is made by the partial reduction of sodium chlorate to chlorine dioxide and the chlorine dioxide's subsequent conversion to sodium chlorite in an alkaline solution in the presence of hydrogen peroxide. This paper evaluates the effectiveness of generating chlorine dioxide gas using Eka Chemical's method of sodium chlorate/hydrogen peroxide/sulfuric acid technology as it compares to the Rio Linda (Vulcan) chlorine gas/25 percent sodium chlorite system process at the El Paso Water Utilities' 40 mgd Canal (Umbenhauer/ Robertson) Water Plant in El Paso, Texas. 0000006947 00000 n Both chemicals have found their uses in health and industrial manufacturing, and both can be purchased from a variety of sources.
