摘要
三乙膦酸铝(Phosethyl-Al)是一种防治果蔬作物疫病和霜霉病的内吸性杀菌剂。它与代森锰锌混合后具有增效作用。关于混剂中三乙膦酸铝的分析方法,仅见消化-比色定磷法的报道。本文参考乙醇顶空气相色谱分析方法,对三乙膦酸铝及其混剂(ND-901)中三乙膦酸铝的顶空气相色谱法进行了系统研究。本方法在国内外尚未见报道。
A new, simple, accurate and sensitive method for the determination of phosethyl-Al and ND-901 by head-space chromatography has been developed. The calibration factor of mancozeb in the mixture is close to 100. The internal standard (ten-butanol) is different from ethanol in salt effects. The recoveries of phosethyl-Al and ND-901 were 99. 53-101.56% and 99.79-102-35%, respectively. The coefficients of variation were 0.56% and 1.02%, respectively.
