| Abstract: | The method for determination of trace Bismuth in soil by microwave digestion soil and graphite furnace a-tomic absorption spectrometry was established.The two ammonium hydrogen phosphate as matrix modifier,pyrolyt-ic coated graphite tube and Zeeman background correction were used.The sensitivity and accuracy of this method in the determination of bismuth were greatly improved.The minimum detectable concentration was 0.02 μg/g,and the recovery was 94.5% ~103.8%.It can meet the requirements of environmental monitoring and analysis. |
