高效液相色谱法测定76%乙·莠·滴辛酯悬乳剂中有效成分含量
Determination of Active Ingredients in 76%Acetochlor·Atrazine·Diclofop-methyl Suspension Emulsion by High Performance Liquid Chromatography
摘要
Abstract
A high performance liquid chromatography(HPLC)method was established for the simultaneous determination of acetochlor,atrazine and 2,4-D isooctyl ester in 76%acetochlor·atrazine·2,4-D isooctyl ester suspension emulsion(SE)under the same chromatographic conditions.The separation was performed on a C18 column,using methanol-phosphoric acid aqueous solution as the mobile phase with gradient elution,and the detection was carried out using a diode array detector(DAD)at a wavelength of 230 nm.The validation results showed that the linear correlation coefficients of acetochlor,atrazine and 2,4-D isooctyl ester were 0.999 1,0.999 2 and 0.999 4,respectively;the standard deviations were 0.004 9,0.005 4 and 0.001 8,respectively;the relative standard deviations(RSD)were 1.54%,1.70%and 1.54%,respectively;and the average recoveries were 99.31%,99.17%and 99.02%,respectively.关键词
