| heal.abstract | A method based on a headspace solid phase microextraction (HS-SPME) technique followed by gas chromatography with flame thermionic and mass spectrometric detection was developed for the determination of seven organophosphorus (OPs) insecticide residues in strawberry and cherry juice samples. The extraction capacities of four fiber coatings, polyacrylate (PA 85 mum), poly(dimethylsiloxane) (PDMS 100 mum), carbowax-divinylbenzene (CW-DVB 65 mum), and poly(dimethylsiloxane)-divinylbenzene (PDMS-DVB 65 mum), have been studied and compared. The method was developed using spiked strawberry and cherry juices in a concentration range of 0.5-50 mug/L The PDMS 100 mum fiber showed good extraction efficiency for the target compounds. An increase in the extraction efficiency of OP insecticides was observed when the parameters affecting the HS-SPME process such as temperature, extraction time, salt additives, stirring rate, pH, and effect of dilution were optimized. Good linearity of compounds was observed in the tested concentration range. The relative standard deviations were found to be <20%. The limits of detection were between 0.025 and 0.050 mug/L. The mean relative recoveries ranged from 82 to 102%. | en |
