摘要：
Imipramine in aqueous solution is extracted into 1,2-dichloroethane as its ion-pair with Methyl Orange in an unsegmented flow system and quantified spectrophotometrically. A linear calibration graph was obtained between 0.79 and 25.3 mug/ml of imipramine. Up to 45 samples/hr can be processed with a RSD of 0.88-1.6%. The method was satisfactorily applied to the determination of imipramine in pharmaceutical preparations.
