| Abstract | ||
| Abstract A batch and flow injection (FI) Spectrophotometric methods have been developed for the determination of adrenaline in aqueous solution and in pharmaceutical ampoules preparation .The methods are based on the reaction of adrenaline with tyramine in presence of potassium metaperiodate as oxidizing agent in neutral solution .The water soluble orange colour produced was measured at 475 nm .Linearty was observed from 0.6 – 25 and from 1 – 70 µg.ml-1 adrenaline with quantification limits of 0.23 and 0.47 µg.ml-1 adrenaline by batch and FI procedure respectively . The effect of chemical and physical parameters have been carfully considered and the proposed methods were successfully applied to the determination of adrenaline in ampoules formulation . | ||
