Abstract:The effective Lead of ginkgo biloba was determinated by hydride generaton-atomic fluorescence spectrometry. The factors that afected the fluorescence intensity of Pb was investigated,including the instrument conditions, medium concentration, current-carrying concentration and prereduetant etc. The results showed that the effective lead of ginkgo biloba was ranged from 0 to 0. 002μg/L and the recovery at three spiked levels were ranged from 87.50%-93.75%.
Keywords:effective lead  hydride generation  atomic fltuorescence spectrophotometry  gingko biloba
