Scope
This document specifies the salicylic acid spectrophotometric method for determining nitrate in water. This document is applicable to the determination of nitrate in surface water, groundwater, and industrial wastewater. For the determination of nitrate in this document, a 10 mm path length cuvette is used. The water sample volume is 50 mL, with a detection limit of 0.077 mg/L and a determination limit of 0.310 mg/L.
