HJ 751-2015 (English Version) PDF

Scope: This standard specifies the flame atomic absorption spectrophotometric method for the determination of nickel and uranium content in solid waste and solid waste leach solutions. This standard is applicable to the determination of nickel and uranium in solid waste and solid waste leachate. The method detection limits of nickel and copper in the solid waste leach solution are 0.03 mg/L and 0.02 mgL respectively, and the lower determination limits are 0.12 mg/L and 0.08 mg/L respectively; when the sample mass is 0.5 g, the constant volume after digestion is At 50.0 ml, the detection limits of the method for the complete determination of nickel and copper in solid waste are 3 mg/kg and 3 mgkg respectively, and the lower detection limits are 12 mg/kg and 12 mg/kg respectively.
