| Abstract：A method for the determination of 25% Dicosulfuron, Atrazine and Dicamba oil-based suspension concentrates by HPLC was developed. The mobile phase was a mixture of methanol, acetonitrile, and 0.3% phosphoric acid aqueous solution(30/30/40, by vol) and the flow rate was set at a rate of 1.0 mL/min; a C18 column and a wavelength of 239nm were used. The standard deviation of Nicosulfuron, Atrazine and Dicamba were 0.029, 0.073, and 0.068, respectively. The relative standard deviation were 0.96%, 0.49%, and 0.97%, while the average recovery were 99.53%, 100.42%, and 99.68%, respectively; and the linear correlation coefficient were 0.999 97, 0.999 96, and 0.999 92, respectively. The method had the advantages of convenience, fast speed, high precision and accuracy, and was suitable for the product quality control . |
