Silver Determination in the Soils by Graphite Furnace Atomic Absorption Spectrometry

Method was established to determine the trace silver in the soils by graphite furnace atomic absorption spectrometry.The experimental condition was optimized.The liner relation of method was good.The limit detection of method was 0.01 mg/kg at preparing digestive solution 25 mL by weighing about 0.25 g of soil sample.The method meets the accuracy requirements for trace silver determination in the soils with confirmation of standard reference samples.
