ASTM D1426

Ammonia Nitrogen In Water

Applicability: ASTM D1426 applies to the determination of ammonia nitrogen in water, including industrial waters and wastewaters. Specifically, it covers the determination of ammonia and ammonium ions in these water types. The standard provides two test methods: a referee method suitable for all types of industrial water and a non-referee method for rapid, routine determinations. Both methods can be applied to surface and industrial waters and wastewaters after distillation.

Purpose: ASTM D1426 provides standard test methods for determining ammonia nitrogen in water. It aims to establish consistent procedures for measuring ammonia concentration, specifically excluding organic nitrogen, in various water samples.
