The speciation of iron, manganese, phosphorus and platinum in aqueous solutions by using ion chromatography coupled with an element selective detector

Abstract

A method is described that employs ion chromatography in combination with d.c. plasma atomic emission spectroscopy to speciate iron, manganese, phosphorus and platinum in aqueous solutions. The element selective nature of the d.c. plasma allows its use as a chromatographic detector for all species of a targeted element eluting from a chromatographic column. This procedure is not only insensitive to matrix effects but is also suitable for monitoring element transformation that can occur as a result of biological or chemical changes.
