Verfahrens-Dokument
Ammonia in the sample reacts with hypochlorite ions which are generated in situ by alkaline hydrolysis of sodium dicholorisocyanurate. This reaction forms monochloramine which then reacts with salicylate ions in the presence of sodium nitroprusside. A blue, indophenol-type compound is formed which is measured colorimetrically at 660 nm.
