Due to the widespread use of toxic chemicals in most workplaces that can lead to toxic effects on human, various chemical extraction technique have been defined for analysis these toxic substances in air, water and biological samples. The purpose of this research is extraction of  toluene and methyl ethyl ketone from aquatic samples with needle trap device and  one commercial sorbent.


In this research, needle trap device was used to extraction of  toluene and methyl ethyl ketone in aquatic samples, so needles(size 20) were packed with PDMS and extraction was done with dynamic headspace needle trap device. Gas chromatography with - flame ionization detector was used to analysis and optimized extraction of two substances were obtained.


Results show that the optimum temperature and time extraction was similar for toluene and methyl ethyl ketone (30 ° C, 30 min), but the reproducibility of results and calibration curve that obtained for toluene was better than methyl ethyl ketone.


Needle trap technique is inexpensive, sensitive and portable also this method has good recovery to extract small amounts of  toluene and methyl ethyketon from aquatic samples with polydimethylsiloxane.
