Scope
Main technical content: This document specifies the rapid graphite digestion-atomic fluorescence method for determining the content of arsenic (As) and mercury (Hg) in soil. This document is applicable to the determination of arsenic and mercury content in soil. When the sampling amount is 0.2 g (dry weight), the detection limit of As determined by this method is 0.02 mg/kg, and the quantitative limit is 0.08 mg/kg; the detection limit of Hg is 0.003 mg/kg, and the quantitative limit is 0.012 mg/kg.
