Determination of organochlorine pesticides and their derivations in water after HS-SPME using polymethylphenylvinylsiloxane-coated fiber by GC-ECD.
Water Res. 2005 Oct; 39(17):4204-10.WR

Abstract

A porous sol-gel polymethylphenylvinylsiloxane-coated fiber was applied to optimize the headspace solid-phase microextraction (HS-SPME) conditions for the analysis of 11 organochlorine pesticides (OCPs) and their derivations in water. Their determination was carried out using gas chromatography (GC) with electron capture detector (ECD). The method developed was applied to the analysis of lake water samples. Detection limits varied from 0.835 to 13.0 ng/l and relative standard deviations (RSD<or=11.8%) were obtained showing that the precision of the method is reliable. The method also showed good linearity for the tested concentration range with regression coefficients (R2) ranging between 0.980 and 0.999. Recoveries for all the analytes ranged from 71.5% to 115.5%. The results demonstrate the suitability of the HS-SPME/GC-ECD approach for the analysis of multi-residue OCPs in water.
