硫解磷定是一种常用的有机磷农药的解毒剂,现行的分析标准为银量法和分光光度法,文献报导的其它方法较少,我们研制成性能较好的碘解磷定电极,采用碘解磷定电极电位法测定碘解磷定原料及针剂的含量时,获得满意结果,电极法较药典法简便快速,准确度高,适于样品的例行分析。 Thiopetigmine is a commonly used organophosphorus pesticide antidote, the current analytical standards for the silver method and spectrophotometry, the literature reported less other methods, we developed a better performance of iodine-phosphorus fixed electrode, When the content of iodine-phosphorus-fixing raw materials and injection was determined by iodine-phosphorous fixed electrode potential method, satisfactory results were obtained. Electrode method was simple, rapid and accurate compared with the pharmacopoeial method. It was suitable for the routine analysis of samples.
