Abstract:The program controlling temperature-hydro dispelling Pb(lead)in the apple sample were studied,and the content of Pb in apple determined by graphite furnace atomic absorption spectrography(GFAAS).Under the circumstances selected in this way,the recovery rate is 92.0% to 107.0% with the deviation reducing to 4.1%.The t test and comparative experiment between the method and the national standard method has proved that there was no obvious difference between them.
Keywords:program controlling temperature  hydro dispelling  graphite furnace atomic absorption spectrography  apple  Pb(lead)
