title: Spectrophotometric determination of promazine with an oxidative column in FIA manifolds.
abstract: A simple flow-injection spectrophotometric method for the determination of promazine is described. The two proposed procedures are based on the oxidation of analyte with a manganese dioxide column. Concentrations of promazine in the ranges 2-20 and 1-6 are determined with a relative standard deviation of 1.0%. The injection rates are 62 and 80 samples h-1, respectively. The influence of foreign species and the determination of promazine in a pharmaceutical formulation are also reported.
