“…Wirt and co-workers (1998) employed an IonPac AS 11 column, hydroxide eluent and suppressed conductivity with ASRS suppressor; the primary advantage of using the more hydrophilic column was that p-cyanophenol was not required in the eluent. Jackson et al (1999) also discussed the suitability of the AS11; they proposed the use of a large loop injection (1000 µg l -1 ) with a Dionex IonPac AS11 column, a 100 mM hydroxide eluent, suppressed conductivity detection and a MDL of 0.3 µg l -1 . One year later, they reported on the development and application of a new anionexchange column for the determination of trace level perchlorate (Jackson et al, 2000).…”

Chloroform and other bromochlorotrihalomethanes were first identified as disinfection byproducts (DBPs) in chlorinated water in 1970s. Since then, many other DBPs have been identified such as haloacetonitriles, haloacetaldehydes, cyanogen halides, aldehydes, ketoacids, chlorite, bromate and other organic and inorganic compounds. Due to their occurrence and potential health risks, the U.S.EPA promulgated the Stage I Disinfectants and Disinfection Byproducts (D-DBP) Rule in 1998. To assist water utilities monitoring DBPs in their finished water, the U.S. EPA published a list of approved analytical methods under the D-DBP Rule. In 1996, the U.S. EPA also promulgated the Information Collection Rule (ICR) to collect brackground information on DBPs and pathogens for the Stage II D-DBP-Rule. Actually 500 DBPs are known but few have been investigated for their quantitative occurrence and health effects. Due to the fact that their identification and quantitation have become extremely important to drinking water companies in order to reduce or remove their presence, other analytical methods different from those proposed by U.S. EPA have been optimized and are now commented in this article.

“…Perchlorate and chlorate were analyzed by an ion chromatograph (Dionex, Sunnyvale, CA) equipped with a Dionex Ionpac AS11 column [16]. NaOH solution (100 mM for perchlorate, 1 mM for chlorate) was used as the eluent and the injection volume was 10 L.…”
