Dionex is pleased to announce the
release of Application Note 268:
Determination of Chelating Agents in Drinking Water and
Wastewater Samples. Chelating agents have
multiple industrial applications and therefore can sometimes be found in
wastewater and drinking water. Some studies suggest that these chelating agents
can have biological impact at concentrations greater than 1 mg/L. Based on
this, some regulatory bodies have specified concentration limits for chelators
in drinking water.
This Application Note describes how to separate four common
chelators easily using a
Dionex IonPac® AS7 column. Using pulsed amperometric detection with a disposable
platinum working electrode, chelating agents were detected below the required
sensitivity. This method features direct and selective detection and was
successfully applied to drinking and wastewater samples.
