HJ 752-2015 (English Version) PDF

Scope: This standard specifies the graphite furnace atomic absorption spectrophotometry method for the determination of calcium, nickel, copper and molybdenum content in solid waste leachate and solid waste. This standard is applicable to the determination of iron, nickel, copper and molybdenum in solid waste leachate and solid waste. The detection limits of the method for determining calcium, nickel, copper and molybdenum in solid waste leachate are 0.1 hgL, 1 hgL, 3 hgL and 2 hg/L respectively, and the lower detection limits are 0.4 hg/L, 4 hgHL, 12 hgIL and 8 hg respectively. /L; when the sampling volume is 0.5 g and the fixed volume after digestion is 50.0 ml, the detection limits of the method for determining the total amounts of anion, tantalum, copper and molybdenum in solid waste are 0.04 mg/kg, 0.2 mg/kg and 0.3 mg/ kg and 0.2 mgy/kg, the lower limits of determination are 0.16 mg/kg, 0.8 mg/kg, 1.2 mg/kg and 0.8 mg/kg respectively.
