A method for determination of the carbaryl pesticide residue in wastewater by high performance liquid chromatography (HPLC). HPLC using Agilent ZORBAX SB-C18 column as a separate column; the use of volume ratio(55:45) of methanol: water as the mobile phase; the use of a diode array detector(DAD) detection at 268 nm at carbaryl residues; pretreatment of water samples using the extraction method is simple and feasible method of operation; laboratory water samples from wastewater, test results show: accuracy relative standard deviation(RSD) was 0.67%, and the recovery rates were in the range of 102 to 112%.
