CHLORINE DIOXIDE CHEMISTRY, REACTIONS, AND DISINFECTION BY-PRODUCTS
Citation:
RICHARDSON, S. D., C. RAV-ACHA, AND G. D. SIMPSON. CHLORINE DIOXIDE CHEMISTRY, REACTIONS, AND DISINFECTION BY-PRODUCTS. Chapter 2, State of the Science of Chlorine Dioxide in Drinking Water. Water Research Foundation and Fondazione AMGA, Denver, CO, , 21-49, (2009).
Impact/Purpose:
(1) Use a toxicity-based approach to prioritize and identify DBPs that show the greatest toxic response. (2) Comprehensively identify DBPs formed by different disinfectant regimes for the 'Four Lab Study'. (3) Determine the mechanisms of formation for potentially hazardous bromonitromethane DBPs.
Description:
This chapter contains two main sections-the first section describes the chemistry and reactions of chlorine dioxide, and the second describes the disinfection by-products (DBPs) of chlorine dioxide and their control. A short section on Research Needs completes this chapter. The section on chemistry and reactions is presented first because it lays the foundation for the reactions that are possible with chlorine dioxide, and in many cases, helps to explain some of the DBPs that have been reported. This chapter is intended to provide an overview of chemistry, reactions, and DBPs of chlorine dioxide and, as such, is not meant to be an exhaustive treatise. An extensive reference list is provided for additional details, especially with regard to the mechanisms of reaction.
