A modification to the extraction-atomic-absorption method for the determination of antimony, bismuth, lead and tin

Abstract

It has been shown that the use of organometallic compounds for the calibration procedure used in the extraction-atomic-absorption determination of antimony, bismuth, lead and tin in metallurgical materials leads to erroneous results at low concentration levels. Results are presented, which demonstrate that the technique is satisfactory when calibrated with solutions that have been taken through the extraction procedure.
