| Abstract: | A GC method for the determination of hymexazol residues in rice husk and brown rice was introduced in this paper. The samples were extracted with acetone and concentrated to dryness then make to volume with ethyl acetate. The hymexazol residues were determined by GC with DB-FFAP column and NP detector. The operation conditions were as follows： injector temperature： 230℃ ; column oven temperature： 200℃; detector temperature： 230℃ ; nitrogen flow rate ： 2mL/min ; hydrogen flow rate ： 3.5mL/min ; air flow rate ： 50mL/min ; make up gas flow rate： 5mL/min. The results showed that the recoveries were 80.4-103.2%, the coefficients of variation were 2.27-4.05%. |
