AN 136: Determination of Inorganic Oxyhalide Disinfection Byproduct Anions in Drinking Water Using IC with the Addition of a Postcolumn Reagent for Trace Bromate Analysis
Description
This application note describes an improved IC method to quantify low levels of oxyhalide DBP anions and bromide in reagent water, bottled water, and finished drinking water. The method uses a Dionex IonPac AS9-HC column and suppressed conductivity detection, followed by postcolumn addition of o-dianisidine (ODA) to enhance visible absorbance detection of the bromate ion. This method allows quantification of all the key oxyhalide anions and bromide at low µg/L levels by using conductivity detection, and the postcolumn addition of ODA. Also refer to AN168 for updated method.| Market: | Environmental |
