Section 2.7 Determination of ammonium: distillation and titration method

Scope

This International Standard specifies a distillation and titration method for the determination of ammonium in raw, potable and waste water.An ammonium nitrogen content of up to 10 mg in the test portion may be determined. Using a 10 ml test portion, this corresponds to a sample concentration of up to A’N P = 1 000 mg/l.
