| Abstract: | The residue analytical method for chlorpyrifos pesticides in cassia by GC was introduced.The Agilent 6890N gas chromatograph was used with DB-1701 and HP-5 capillary column,flame photometric detector(FPD) and electron capture detector(ECD),using external standard method.The pesticides were cleaned-up with alumina neutral to get the good effect and save examination cost,The average recovery was 86.7%~93.4%,All the technical items conformed to the requirements. |
