| Abstract: | A method for the determination of mercury in snake powder by hydride generation-atomic fluorescence spectrometry has been established.Analytical conditions,including main lamp current,Carrier gas flow rate,Shield gas flow rate and delay/integration time were optimized.The detection limit of present method is 0.7 pg/mL mercury under optimized conditions.Relative standard deviations are 4.1% and 0.9% for 0.3 ng/mL and 1 ng/mL mercury standard solution,respectively.The recoveries for sample determination are between 87% and 110%. |
