| Abstract: | A high performance liquid chromatographic method was used for the determination of atrazine in water. After extracted from samples by C18 solid-phase extraction column, the atrazine was determined by HPLC.The mobile phase was methanol-water,and the detection wavelength was 220 nm.In the range of 0.1-5.0 mg/L,the correlation coefficient was 0.999 5.The recoveries were 82.0%-90.3%. The relative standard deviation was 1.3%. |
