Chlorite and chlorate are DBPs resulting from the use of chlorine dioxide as a disinfectant and for odour/taste control in water. 1982 Dec;46:13-7. Chlorite and chlorate ions can also be formed during the generation process of chlorine dioxide, where the generation technology and the generator “tuning” will affect the levels of chlorite and chlorate fed into the drinking water. 0000002675 00000 n Collections are surprisingly limited '', when followed by addition of Potassium chloride s in a Name followed addition. background: none !important; Différence principale - Chlorure vs chlorate. Subsequently, the majority of chlorine dioxide added to drinking water will eventually form chlorite. Authors D Couri, M S Abdel-Rahman, R J Bull.

Used in the United States and equipment primarily used for industrial use chlorite ion but chlorate ion 35.45. 0000013693 00000 n Minimizing the inorganic by‐products chlorite ion and chlorate ion in drinking water treated with chlorine dioxide is important if Cl0 2 is to remain a viable alternative in potable water treatment. Our equipment specialists are ready to answer any and all of your questions.

The free acid, chlorous acid HClO2, is the least stable oxoacid of chlorine and has only been observed as an aqueous solution at low concentrations. Lubbers, J.R., Chauhan, S. and Bianchine, J.R. (1981). 0000006947 00000 n First, the explosively unstable gas chlorine dioxide , ClO 2 is produced by reducing sodium chlorate with a suitable reducing agent such as methanol, hydrogen peroxide, hydrochloric acid or sulfur dioxide. Chlorate standard concentrations vs. area of peak around 5.6 minutes ( ). Chlorite is a DBP formed with chlorine dioxide treatment, and it is currently regulated at 1.0 mg l −1 in the United States.

Chlorite standard concentrations vs. area of peak around 3.6 minutes ( ). 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.
