Flow Injection HGAAS Determine Trace Hg in Human Hair

Objective To found new methods of Hg in human hair.Methods This methods adopt flow infection hydride generation atomic absorption spectroscopy(HGGAAS)teamwork technic to determine trace Hg in the human hair.Results The method detection limit is 0.1ng/g.The linearity scope is 0.000~2.520μg/g.The recovery is 92%~98%.The relative standard deviation is 1.4%~3.4%.Conclusion It is simple,convenient,and of good precision and high accuracy.It is a very good methods for mensuration of the Hg in human hair.
