A Dynamic Study of Daconil Residues in Folium Isatidis
百菌清在大青叶中的残留动态研究

Authors studied pesticide daconil residues in Folium Isatidis in a dynamic manner.Daconil was separated directly by EQYUTY-1701 capillary column using GC chromatography with an ECD detector.Daconil recoveries at three dif- ferent spiking levels were 88.41%,100.09%,and 85.28% respectively.Daconil dynamics was described in a two- compartment model.Both low and high-level daconil in Folium Isatidis had a 17-day safety interval.It is concluded that the method is convenient,accurate,and specific.
