behaviour of chlorpromazine has been examined in phosphate buffers in aqueous as well as micellar media at a pyrolytic graphite electrode surface. Two oxidation peaks were obtained in linear sweep voltammetry of chlorpromazine. The first peak corresponds to the formation of the cationic free radical, which on further 1e−-oxidation gives a dication. The spectroscopic changes and kinetics of the cationic
已经在热解石墨电极表面的水性和胶束介质的磷酸盐缓冲液中检查了氯丙嗪的电化学行为。在氯丙嗪的线性扫描伏安法中获得了两个氧化峰。第一个峰对应于形成的阳离子自由基,其上进一步1E -氧化作用给出了一个二价阳离子。在两种介质中研究了氯丙嗪电氧化过程中产生的阳离子自由基和阳离子物种的光谱变化和动力学。计时电流法研究了该药的衰变,发现该药遵循一阶动力学,半衰期约为25毫秒。表面活性剂会影响 E p和 i p价值观。已经发现阴离子表面活性剂 SDS 可催化自由基阳离子和阳离子的反应。
