皮蝇磷是一种防治牲畜体内外寄生虫的特效药物,还可作农药和家用卫生品使用。文献中,用色谱法,分光光度法和薄层色谱-比色法等测定皮蝇磷在各种情况下的浓度已有许多报导。作者在1964年首先用极谱法研究了皮蝇磷的测定法。由于2、4、5-三氯酚是合成皮蝇磷时需要过量加入的一种基本原料,合成后虽经分离回收,有时仍难免有少量三氯酚混
Pipi is a potent drug used to control parasites inside and outside livestock and also used as a pesticide and household hygiene product. In the literature, there have been many reports on the determination of pectinifera in various situations by chromatography, spectrophotometry and thin-layer chromatography-colorimetry. In 1964, the author first used polarography to study the assay of Pipi. Since 2,4,5-trichlorophenol is a basic raw material that needs to be added excessively when synthesizing skin fly phosphorus, although it is sometimes separated and recovered after synthesis, it is still sometimes inevitable that a small amount of trichlorophenol is mixed
