Sodium hypochlorite (NaOCl-) combines with ammonia present in the sample to produce NH2C1 and OH" ions. Sodium nitroprusside catalyses the reaction. The NH2C1 in the presence of 3 0H~ combines with phenol and forms a quinonoid complex. This quinonoid complex combines with another phenol molecule to form indophenol, a coloured compound. The colour thus formed is directly proportional to the ammonia present in the sample (Boltz & Howel, 1978).
