DETERMINATION OF TRACE LEAD IN SPIRITS BY HYDRIDE GENERATION-ATOMIC FLUORESCENCE SPECTROMETRY

Tang Lianxian (Jinhua Measurement and Test Institute for Quality and Technique Supervision, Jinhua 321000, China)Wu Xiao(Jinhua City CHELBI Engineering Consulting Co.ltd, Jinhua 321000, China)Zheng Shaocheng(Zhejiang Normal University, Jinhua 321000, China)  
A method for determination of lead in spirits by hydride generation-atomic fluorescence spectrometry was established. The infection factors were studied, and the best test conditions were selected. The linearity range for the determination of lead was 0-20.0 μg/L, and the limit of detection was 1.0 μg/L. The recoveries were in the rang of 94.0%-108.0%. The relative standard deviations were 3.28%-4.03%(n=11).
