AU122: The Determination of Iodide in Brine
DescriptionIn this Application Update, ion chromatography coupled with pulsed amperometric detection is used to determine iodide in brine (approximately 30% sodium chloride). This method is specific, sensitive, and rapid. Sample preparation is a simple sample dilution. Iodide is separated on the Dionex IonPac AS11 column, which contains a hydrophilic resin that is well suited to the chromatography of iodide, a relatively hydrophobic anion. Using a nitric acid eluent, the iodide ion elutes from the column in under five minutes.
