1.1 These test methods cover the atomic absorption determination of silver in water. Section 34 on Quality Control pertains to these test methods. Three test methods are given as follows:
|
| Concentration | |
|
| ||
| Test Method A—Atomic Absorption—Chelation-ExtractionA | 1 to 10 μg/L | 7 – 15 |
| Test Method B—Atomic Absorption—Direct | 0.1 to 10 mg/L | 16 – 24 |
| Test Method C—Atomic Absorption—Graphite Furnace | 1 to 25 μg/L | 25 – 33 |
