Scope

This Standard specifies the microwave dissolution/atomic fluorescence spectrometry
for the determination of mercury, arsenic, selenium, bismuth, and antimony in soil and
sediment.
This Standard applies to the determination of mercury, arsenic, selenium, bismuth, and
antimony in soil and sediment.
When the sample size is 0.5 g, for mercury, the detection limit of this method is 0.002
mg/kg, and the lower limit of determination is 0.008 mg/kg; for arsenic, selenium,
bismuth, and antimony, the detection limit is 0.01 mg/kg, and the lower limit of
determination is 0.04 mg/kg.
