1.1 ,These test methods cover the determination of dissolved and total recoverable cadmium in water and wastewater by atomic-absorption spectrophotometry and differential pulse anodic stripping voltammetry.2 Section 44 on Quality Control pertains to these test methods. Four test methods are included as follows:
| , | Concentration | Sections |
| Test Method A—,Atomic Absorption, | 0.05 to 2.0 mg/L | 7 to 15 |
| Test Method B—,Atomic Absorption, | 5 to 200 μ,g/L | 16 to 24 |
| Test Method C—,Differential Pulse | 1 to 100 μ,g/L | 25 to 34 |
| Test Method D—,Atomic Absorption, | 2 to 10 μ,g/L | 35 to 43 |
