AN254: Determination of Total Phosphorus in Wastewater Using Caro's Reagent and Ion Chromatography

Instrument Type: IC

Here, two IC methods are presented for the determination of phosphorus content in wastewater. The sample's organic and inorganic phosphorus are converted to orthophosphate by treatment with Caro’s reagent before analysis by IC. Converting organic and inorganic phosphorus to orthophosphate allows phosphorus to be determined by ion chromatography (IC) with suppressed conductivity detection.
