Standard Test Methods for Ammonia Nitrogen In Water

Organization: ASTM International
Publication Date: 10 December 1998
Status: inactive
Page Count: 5
ICS Code (Examination of water for chemical substances): 13.060.50
scope:

1.1 These test methods cover the determination of ammonia nitrogen, exclusive of organic nitrogen, in water. Two test methods are included as follows:

Section Test Method A-Direct Nesslerization 7 to 15 Test Method B-Selective Ion Electrode 16 to 24

1.2 Test Method A is used for the routine determination of ammonia in steam condensates and demineralizer effluents.

1.3 Test Method B is applicable to the determination of ammonia nitrogen in the range from 0.5 to 1000 mg NH - N/L directly in reagent and effluent waters. Higher concentrations can be determined following dilution. The reported lower range is based on multiple-operator precision. Lower limits have been obtained by two of the twelve laboratories participating in the round robin.

1.4 Both test methods A and B are applicable to surface and industrial waters and wastewaters following distillation. The test method for distillation given in Appendix X1 has been used in the past to meet requirements for predistillation of samples being analyzed for ammonia.

1.5 This standard does not purport to address all of the safety problems, 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.

1.6 The Distillation Method now appears as Appendix X1 and is provided as nonmandatory information only. The Automated Colorimetric Phenate Method has been discontinued; refer to Appendix X2 for historical information.
