Determination of antimony in geological samples using hydride generation and direct current plasma atomic emission spectrometry

Abstract

A hydride generation technique coupled with direct current plasma atomic emission spectrometry has been used for the determination of antimony. The optimum instrumental parameters and the calibration graphs and detection limits (established for standard solutions) were determined at three different wavelengths. The interference effects of other hydride-forming elements on the determination of antimony were investigated and the method was tested on a number of Geological Survey reference materials.
