Spectrophotometric determination of alpha naphthol beta naphthol and oxine in aqueous solution

, : Spectrophotometric determination of alpha naphthol beta naphthol and oxine in aqueous solution. Microchemical Journal 33(1): 78-80

Diazotized orthanilic acid reagent has been devised as a novel chromogen for the trace determination of .alpha.-naphthol, .beta.-naphthol, and oxine in aqueous solution. The developed method is characterized by simplicity and rapidness and does not resort to either temperature control or solvent extraction.
