Scope

This standard specifies the use of atomic absorption spectrophotometry to determine the contents of copper, lead, zinc, zinc, and manganese in coal mine water. This standard is applicable to the determination of copper, lead, zinc, cadmium and manganese in coal mine water. The determination ranges are copper: 0.5 mg/L ~ 5.O mg/L; lead: direct method 2.5 mg/L ~ 20.O mg/L, extraction method 0.04 mg/L ~ 2.O mg/L: zinc : 0.05mg/L～1.5mg/L: Cadmium: 0.04mg/L～1.O mg/L by direct method, less than 0.004mg/L by extraction method; Manganese: 0.1mg/L～4.O mg/L.
