The direct current polarographic behaviour of the bromometric oxidation product of certain penicillins has been investigated. The oxidized products give a well defined cathodic wave with E1/2 = 0.6 V vs saturated calomel electrode (SCE). The nature of the wave and the electrode reaction have been evaluated. A procedure was developed for investigation of the penicillins either in the pure state or in dosage forms. The results were compared with those obtained with the official methods.
对某些青霉素的溴氧化产物的直流极谱行为进行了研究。氧化产物给出了一个明确的阴极波，相对于饱和甘汞电极（SCE），其半波电位E1/2 = 0.6V。对该波的性质和电极反应进行了评估。开发了一种用于研究纯态或剂型青霉素的方法。将结果与用官方方法获得的结果进行了比较。
