RAPID DETERMINATION OF LEAD IN WATER BODY BY HYDRID GENERATION-ATOMIC FLUORESENCE SPECTROMETRY

A rapid detection method of lead in water body by hydride generation-atomic fluorescence spectrometry has been developed. The optimum determination factors have been selected. The linear range of calibration curve for lead is 0～100 ng/mL and the detection limit of lead is 0.072 9 ng/mL. The recoveries of standard addition are 94.71% ～ 99.86 %. The method is characterized by simple and fast operation, lower detection limits, higher sensitivity and higher precision.
