Summary
The document specifies the determination of nitrogen compounds as nitrate in water subsequent to digestion using peroxodisulfate in a buffered alkaline system. Determination is by flow analysis following reduction of nitrate to nitrite (reference method). Additional methods of determination are included in this document for information. Dissolved nitrogen gas is not determined. This method is applicable for all types of water provided TOC < 40 mg/l and CSB < 120 mg/l.
