title: Flow injection spectrophotometric determination of promazine.
abstract: A method for the spectrophotometric determination of promazine by flow injection analysis is reported. The procedure is based on the reaction of promazine with molybdophosphoric acid. Concentrations of promazine in the range 1-25 ppm have been determined with a relative standard deviation of 1.8% at 10 ppm (n = 20). The method was applied to the determination of promazine in injections and compared favourably with an independent reference method based on spectrophotometry.
