Sequential determination of arsenic, antimony and bismuth in low-alloy steels by hydride generation inductively coupled plasma atomic emission spectrometry

Abstract

The analysis of four NBS reference low-alloy steels for arsenic, antimony and bismuth is described. The method involves acid dissolution followed by hydride generation coupled with sequential determination by inductively coupled plasma atomic emission spectrometry. Chemical interferences were found to be negligible, and direct determination against synthetic standards was used. The method allows the rapid determination of the three elements in the same solution.
