Abstract
We have developed a solid-phase extraction method for determination of three pesticides, thiuram, simazine and benthiocarb, in distilled water, river water and industrial waste water by high performance liquid chromatography (HPLC) with ultraviolet detecter (UV) . As a result, good linearity of the calibration curve was obtained in the concentration range from 0.1 mg/l to 1 mg/l. Acetone was recommended for the elution of the pesticides from the solid phases. The recoveries for three pesticides from river water and industrial waste water at a concentration of 0.1 mg/l was 83.3-91.6 %, and coefficient of variation was 4.3-6.0 % by cartrige solid-phase extraction method. This analytical method could be successfully applied to the determination of three pesticides in river water and industrial waste water.
