Determination of malathion by dispersive liquid liquid microextraction combined with ion mobility spectrometry Farhad Riahi December 17 2012 Department of Chemistry Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Lanquage PersianSupervisor Mohammad Taghi JafariEmail jafari@cc iut ac irAbstract In this study for the first time analysis of malathion was done by combining dispersiveliquid liquid microextraction DLLME with corona discharge ionization ion mobilityspetrometry CD IMS DLLME CD IMS with low cost inexpensive maintenance and very fastanalysis makes an attractive technique for the determination of malathion in environmental andagricultral samples In this extraction process a mixture of 45 L carbon tetrachloride extractingsolvent and 1 0 mL methanol disperser solvent was rapidly injected into the 5 0 mL aqueoussample containing the analyte After centrifuging 5 min at 3000 rpm the fine droplets ofcarbon tetrachloride were sedimented in the bottom of the conical test tube Sedimented phasewas direct injected into the CD IMS for analysis Some important parameters such as kind andvolume of extraction and disperser solvent feasibility direct injection of sedimented phase toIMS instrument salt addition and effect of pH were investigated and optimized Under theoptimum extraction condition the enrichment factors and extraction recoveries 150 and 81 respectively The methods yielded a linear range in the concentration from 4 to 200 g L thelimit of detection were1 83 g L respectively and the relative standard deviations RSD were7 6 This method could be successfully applied for the determination of malathion pesticides inapple surface water and underground water
