Ultrasonication assisted development of new greener method for extraction of cypermethrin and transfluthrin from various samples: A forensic approach

Abstract

In present work, we developed an extraction method of two pyrethroids viz., cypermethrin and transfluthrin from soil, cloth pieces and household insecticides by using ultrasonicator. Extractions were done in xylene and ethanol solvents. Confirmation of pyrethroids was performed using thin layer chromatography (TLC), UV-visible, FT-IR spectroscopy and LC-MS.
