Abstract
A method for the spectrophotometric determination of promazine by flow injection analysis is reported. The procedure is based on the reactio n of promazine with molybdophosphoric acid. Concentrations of promazin e 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 de termination of promazine in injections and compared favourably with an independent reference method based on spectrophotometry.
