Abstract:

A method for the determination of eight organophosphorus pesticide residues (OPs) in apple juice concentrate by fiber solid phase microextraction (SPME) coupled with gas chromatography was developed. The extraction conditions were optimized. The average recoveries and relative standard deviations of the pesticides were 69.2% to 103.2% and 0.98% to 4.8% respectively. The detection limits of OPs were in the range of 0.4 ng/L to 4.1 ng/L. In conclusion, this method is rapid, accurate and easy for determining pesticides residues in apple juice concentrate.

Key words: solid phase microextraction (SPME), gas chromatography (GC), apple juice concentrate, organophosphorus pesticides, residues
