Due to the environmental potential and human toxicity of pesticides and pyrethroids, development and optimization of sensitive extraction methods for these compounds are required.
When using SDME procedure, it is necessary to optimize parameters that control mass transfer and hence improve the efficiency of the procedure [9].
Usually the parameters to be optimized are type of extraction and time, solvent, stirring speed, ionic strength, pH, temperature effect of the aqueous phase and the drop volume of extraction solvent.
Therefore, the aim of this study was to develop and validate a sensitive SDME/GC–MS method to determine some widespread used organophosphate and pyrethroid pesticides in water samples.
