| Abstract: | A method was established for determination of lead in soil samples by Graphite Furnace Atomic Absorption Spectrometry （GFAAS） with planetary ball mills preparation and microwave digestion. The linearity was good with a range of 0μg/L - 10. 0μg/L. The detection limit was 0. 10 mg/kg for the sample weighed 0. 5 g and diluted to 50 ml in volume. The RSD in the soil samples test was below 4% and the recoveries were from 91.4% to 102%. |
