Studies on Determination of Trace Lead by Metastable Energy Transfer Emission Spectroscopy

Abstract

Abstract: The determination of trace lead with metastable energy transfer emission spectrometry is describedThe active nitrogen is produced in a microwave discharge SurfatronThe sample solution was introduced with an electrothermal vaporization systemThe experimental parameters affecting the determination of lead were examinedThe detection limit of lead line at 283.3 nm is 0.12 ngThe method has been applied to the analysis practical samples and the result is satisfactoryThe mechanism for the metastable energy transfer of active nitrogen induction by Surfatron was studied and discussed.

Key words: Lead, Microwave discharge, Metastable energy transfer, Emission spectrometry
