Disinfecting water with chlorine dioxide eliminates trihalomethane formation but generates several contaminants of its own. Government regulations under consideration would require the removal of these by‐products to levels for which no detection methods have existed. Chemists at the Miami University of Ohio have developed a method to measure chlorate, chlorite, and hypochlorite ions at levels of less than 1 mg/L. The detection accuracy range is ±3 percent.
