Liquid chromatographic determination of benomyl in water samples after dispersive liquid-liquid microextraction.
A dispersive liquid-liquid microextraction (DLLME) method combined with solvolysis reaction for extraction of the carbamate fungicide benomyl as carbendazim from water samples is described. The method is based on the extraction of benomyl from acidified sample solution and its conversion into carbendazim via solvolysis reaction with DMF as organic solvent. The proposed DLLME method was followed by HPLC with fluorimetric detection for determination of benomyl. The proposed method has good linearity (0.998) with wide linear dynamic range (0.01-25 mg/L) and low detection limit (0.0033 mg/L), making it suitable for benomyl determination in water samples.
