Abstract
It is difficult to meet the detection limit of "the specification of multi-purpose regional geochemical survey (1∶ 2500000)" for Hg in the samples.The cold atomic fluorescence spectrometry was chosen to analyze the Hg element concentration of the samples.The working conditions such as lamp current,negative pressure,carrier gas flow and atomization temperature was optimized.The results showed optimized method meets the analysis method requirement of "the specification of multi-purpose regional geochemical survey (1∶ 2500000)".The Method detection limit is 0.19 ng/g.The △lgC (n =12) ofGBW07301a,GBW07428 and GBW07426 is 0.000,0.030 and 0.043,respectively.The RSD (n =12) of the three standard materials is 4.95％ and 4.33％,6.98％,respectively.关键词
