- Scope
- This standard specifies the method for the determination of copper, lead, zinc, tin, nickel, and cobalt by resin-enriched flame atomic absorption method. This standard applies to the determination of copper, lead, zinc, tin, cobalt and nickel in groundwater. The minimum detection amounts (ug) are: copper 2.5, lead 3.1, zinc 2.5, cadmium 0.25, diamond 2.5, and nickel 2.5. If a 250mL water sample is taken and enriched 10 times, the minimum detection concentrations (mg/L) are: copper 0.010, lead 0,013, zinc 0.007, cadmium 0.001, cobalt 0.010, and nickel 0.010. The upper limits of determination (mg/L) are: copper 0.20, lead 0.25, zinc 20, cadmium 0.20, diamond 0.20, and nickel 0.20.
