## Abstract A new method was developed for determination of methomyl in water samples by combining a dispersive liquid–liquid microextraction (DLLME) technique with HPLC–variable wavelength detection (VWD). In this extraction method, 0.50 mL of methanol (as dispersive solvent) containing 20.0 μL of
