WK42422 - New Test Method for Determination of Ammonia Nitrogen by Semi-Automated Gas Diffusion Colorimetry

Work Item

ASTM WK42422

New Test Method for Determination of Ammonia Nitrogen by Semi-Automated Gas Diffusion Colorimetry

1. Scope

1.1 This test method is for the determination of ammonia nitrogen in surface water, municipal and industrial wastewater, seawater, and potassium chloride soil extracts. A gas diffusion step eliminates the need for a preliminary distillation. 1.2 The applicable range of this test method is 0.01-1.00 mg/L as nitrogen or 0.50-10 mg/L as nitrogen. Extend the range to higher concentrations using sample dilution. 1.3 The analyst should be aware that precision and bias statements included may not necessarily apply to the sample being tested. 1.4 Units-The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. 1.5 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.

Keywords

ammonia nitrogen; U.S. Environmental Protection Agency; wastewater

Rationale

This standard will be developed with the intent for inclusion at 40 CFR Part 136.3 allowing its use for compliance reporting of ammonia nitrogen. End users are environmental laboratories.
