Scope: This standard specifies the graphite furnace atomic absorption spectrophotometric method for the determination of pins and pots in solid waste and solid waste leachate. This standard is applicable to the determination of lead and pot in solid waste and solid waste leachate. When the solid waste sampling volume is 0.5 g and the fixed volume after digestion is 25 ml, the method detection limits of lead and pot are 0.3 mgkg and 0.1 mgkg respectively, and the lower determination limits are 1.2 mg/kg and 0.4 mgkg respectively. When the sampling volume of the solid waste leachate is S0 ml and the volume is adjusted to $0 ml after digestion, the detection limits of the pin and pot methods are 0.9 ng/L and 0.6 hgIL respectively, and the lower determination limits are 3.6 hg and 2.4 hg/L respectively. .
