Hydride Preconcentration for Inductively Coupled Plasma Optical Emission Spectrometry.

Abstract

Studies are presented describing application of the NaBH4 reduction of soluble arsenite to form arsine as a preconcentration approach for ultra-trace level arsenic analysis by inductively coupled plasma optical emission spectrometry (ICP-OES). Specialized analyte introduction techniques are described for elimination of reaction by-products that would normally extinguish a medium power plasma discharge. Approaches are presented that eliminate the need for background correction and facilitate superior arsenic sensitivity in a relatively inexpensive ICP system. (Author)
