A Simple and Inexpensive Kit for Measuring Total Trihalomethanes and Total Haloacetic Acids in Drinking Water

摘要

While there are a number of analytical methods that can be used for compliance monitoring ofrntrihalomethanes and haloacetic acids, most are relatively complex and expensive to perform.rnMethods for HAAs typically involve cumbersome extraction steps, followed by complicatedrnderivatization and analysis procedures. For small to midsized utilities, the cost of buying therninstruments and hiring someone to operate and maintain them is often prohibitive. Manyrnoperators and process engineers recognize the need for some sort of THMs/HAAs meter,rnanalogous to a pH meter. This paper presents a “meter” in the form of a portable, relativelyrninexpensive commercially available kit. This kit, called the Disinfection By-Product RapidrnResponse Kit, is capable of predicting the concentrations of Total THMs and Total HAAs onsiternwith minimal effort or expense. Thus, operators and process engineers can use it to respondrnin real-time to changes in trihalomethane and haloacetic acid concentrations as they occur.
