摘要：

A polarographic method is described for the simultaneous determination of ascorbic acid and dipyrone in dosage forms. The method is based on the anodic polarographic waves produced by both compounds in Walpole acetate buffer (pH 3.6). The separation of the two waves (> 0.65 V) is sufficient to allow accurate measurements. The proposed method was successfully applied to the analysis of commercially available ampules, and the results obtained were of satisfactory accuracy and precision.
