本标准规定了测定固体废物和固体废物浸出液中总铬的火焰原子吸收分光光度法。
本标准适用于固体废物和固体废物浸出液中总铬的测定。
Scope
This standard specifies the flame atomic absorption spectrophotometric method for the determination of total chromium in solid wastes and solid waste leach solutions. This standard is applicable to the determination of total chromium in solid waste and solid waste leachate. When measuring solid waste, the sample amount is 0.2 g, and the constant volume is S0 ml, the detection limit of this method is 8 mg/kg, and the lower limit of determination is 30 mgy/kg. For the determination of solid waste leachate, when the constant volume is S0 ml, the detection limit of this method is 0.03 mgIL, and the lower limit of determination is 0.12 mg/L.
