ASTM-D1886:2008 Edition

1.1 These test methods ^{, ,} cover the atomic absorption determination of nickel in water and wastewaters. Three test methods are given as follows:

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 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4 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 Note 4, 11.7.1, 21.9, 23.7, and 23.10.

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

7.1 This test method covers the determination of dissolved and total recoverable nickel and has been used successfully with reagent water, tap water, river water, lake water, ground water, a refinery effluent, and a wastewater.

7.2 This test method is applicable in the range from 0.1 to 10 mg/L of nickel. The range may be extended upward by dilution of the sample.

17.1 This test method covers the determination of dissolved and total recoverable nickel and has been used successfully with reagent water, tap water, river water, artificial seawater and a synthetic (NaCl) brine.

17.2 This test method is applicable in the range from 10 to 1000 ? g/L of nickel. The range may be extended upward by dilution of the sample.

27.1 This test method covers the determination of dissolved and total recoverable nickel and has been used successfully with reagent grade water, lake water, river water, well and filtered tap water, and a condensate from a medium Btu coal gasification process. It is the user’s responsibility to ensure the validity of this test method to other matrices.

27.2 This test method is applicable in the range from approximately 5 to 100 ? g/L nickel using a 20- ? L injection. The range can be increased or decreased by varying the volume of sample injected or the instrumental settings. High concentrations may be diluted but preferably should be analyzed by direct aspiration atomic absorption spectrophotometry (see Test Method A).

27.3 The analyst is encouraged to consult Practice D 3919 for a general discussion of interferences and sample analysis procedures for graphite furnace atomic absorption spectrophotometry.
