SUPERSEDED (see Active link, below)
ASTM D1068
1. Scope
1.1 These test methods cover the determination of iron in water. Procedures are given for determining total iron, dissolved iron, and ferrous iron. Undissolved iron may be calculated from the total iron and dissolved iron determinations. The test methods are given as follows:
Range | Sections | |
Test Method AAtomic Absorption, Direct | 0.1 to 5.0 mg/L | 7 to 15 |
Test Method CAtomic Absorption, Graphite Furnace | 5 to 100 ?g/L | 16 to 24 |
Test Method DPhotometric Bathophenanthroline ? g/L | 40 to 1000 ?g/L | 25 to 36 |
1.2 It is the user's responsibility to ensure the validity of these test methods to waters of untested matrices.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazards statements are given in Note 3, section 11.7.1, and section X1.1.2.
1.3 Two former photometric test methods were discontinued. See Appendix X2 for historical information.
