Significance and Use

These test methods are useful for measuring organic nitrogen and ammoniacal nitrogen, which are essential growth nutrients.

Nitrogen compounds are widely distributed in the environment. Sources of nitrogen include surface-applied fertilizers, cleaning products, and drinking water treatment aids. Because nitrogen is a nutrient for photosynthetic organisms, it may be important to monitor and control discharge into the environment.

Scope

1.1 These test methods cover the determination of total Kjeldahl nitrogen. The following test methods are included:

Sections
Test Method A-Manual Digestion/Distillation8 to 14
Test Method B-Semiautomated Colorimetric Bertholt15 to 23

1.2 The analyst should be aware that precision and bias statements included may not necessarily apply to the water being tested.

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.
