sodium vanadte nanoparticles were synthesized with a hydrothermal method for the micro solid-phase extraction of diazinon. After extraction, Ion mobility spectrometry (IMS) was used for the determination of the analyte in water samples . The effects of experimental parameters such as sorbent amount, solvent type, Solvent volume, salt effect, extraction and desorption conditions on the extraction efficiency of the sorbent were investigated.. The linearity range of the method was 3.0-200 fordiazinon. The recovery of the analyte was in the range of 94.0-103.0 for water samples, respectively. Also, the relative standard deviations were in the range of 4-8 % for water samples, respectively. The limits of detection were 1 for diazinon, respectively.
