| Abstract: | A analytical method was established for the determination of selenium in lead-antimony alloy by hydride generation-atomic fluorescence spectrometry.The sample was dissolved by 33%nitric acid and tartaric acid,and matrix lead was eliminated by lead sulfate precipitation,and selenium was directly measured in the medium of 40%hydrochloric acid.The influences of optimum conditions,lead and coexistent elements on the determination of selenium were investigated.The relative standard deviations were 6.52%-9.34%.The accuracy and precision of results meet the demands,and the method is practical. |
