Full Description

1.1 These test methods 2,3,4 cover the atomic absorption determination of nickel in water and wastewaters. Three test methods are given as follows:

Concentration Range Sections Test Method A-Atomic Absorption, Direct 0.1 to 10 mg/L 7 to 15 Test Method B-Atomic Absorption, Chelation-Extraction 10 to 1000 [mu]g/L 16 to 24 Test Method C-Atomic Absorption, Graphite Furnace 5 to 100 [mu]g/L 25 to 33

1.2 Test Methods A, B, and C have been used successfully with reagent grade water and natural waters. Evaluation of Test Method C was also made in condensate from a medium Btu coal gasification process. It is the user's responsibility to ensure the validity of these test methods for other 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. For specific hazards statements, see Notes 4, 6, 9, and 14.

1.4 Two former colorimetric test methods were discontinued. Refer to Appendix X1 for historical information.
