HJ 750-2015 (English Version) PDF

Scope: This standard specifies the graphite furnace atomic absorption spectrophotometric method for the determination of total chromium in solid waste and solid waste leach solutions. This standard is applicable to the determination of total waste in recycled waste and solid waste leachate. When measuring solid waste, the sample volume is 0.2 g, the fixed volume is S0 ml, and the injection volume is 20, the detection limit of this method is 0.2 mgkg, and the lower determination limit is 0.8 mg/kg. For the determination of solid waste leachate, when the constant volume is 50 ml and the input volume is 20 times, the detection limit of this method is 0.7 ngL, and the lower limit of determination is 2.8 ng/L.
