Dionex Demonstrates Determination of Total Phosphorous in Wastewater

Dionex (USA) is pleased to announce the release of an application on the determination of total phosphorous in wastewater. Application Note 254: Determination of Total Phosphorous in Wastewater Using Caro’s Reagent and Ion Chromatography describes two IC methods, one with simple carbonate/bicarbonate eluent preparation and a second method that uses generated potassium hydroxide eluent and has the high reproducibility of an RFIC™ system.

Phosphorous in the environment is beneficial for many biological processes, but too much phosphorous can create an imbalance in the ecosystem. Monitoring the concentration of phosphorous in the environment is a good indictor because higher than normal concentrations lead to environmental problems. AN 254 demonstrates accurate measurement of the total phosphorous content of a wastewater sample using a Reagent-Free™ IC (RFIC) system with all its benefits, including excellent retention time reproducibility for accurate peak identification, and time and labour savings by eliminating eluent preparation and associated errors.
