摘要: A method for determination of metrafenone residues in bitter gourd and soil was developed. All samples were extracted with ethyl acetate, purified with the glass column of florisil and NH2-SPE column, analyzed by gas chromatography with electronic capture detector (GC-ECD). The results showed that it had good linearity in the range of 0.01-2 mg/L and the correlation coefficient (r) was 0.9999. The average recoveries of metrafenone in bitter gourd and soil were 83.51-91.75% and 84.76-91.72% with the relative standard deviation of 3.48-9.18% and 4.23-7.25%, respectively. The limit of detection was estimated to be 0.005 mg/kg, the minimum concentration of detection in bitter gourd and soil was 1 x 10(-2) mg/kg. (C) 2015 Elsevier Ltd. All rights reserved.
