度米芬(Domiphen Bromide)是一种阳离子表面活性杀菌剂,其结构式为:测定方法有碘酸钾法、铁氰化钾法、四苯硼钠双相滴定法等。前两种方法操作繁琐,双相滴定法近终点时必须剧烈振摇,终点不易观察,且甩较大量氯仿既不经济又对人体有害。交流示波极谱四苯硼钠沉淀滴定法,可用于测定含氮有机药物。本文研究了交流示波极谱滴定法测定度米芬含量,方法准确,简单易行,终点灵敏直观。
Domiphen (Bromide) is a cationic surfactant fungicide, the formula is: determination of potassium iodate method, potassium ferricyanide, tetraphenyl boron biphasic titration and so on. The first two methods of operation cumbersome, biphasic titration method near the end must be violently shaken, the end is not easy to observe, and rejection of a large amount of chloroform is neither economical nor harmful to the human body. AC Oscillopolarographic tetraphenyl boron precipitation precipitation method, can be used for the determination of nitrogen-containing organic drugs. In this paper, the exchange oscillopolarographic titration method for the determination of dipifene content, accurate, simple, easy to use endpoint sensitive and intuitive.
