Abstract
A quantitative analytical method was developed for the determination of 30%picloram·clopyralid·aminopyralid soluble concentrate(SL)in this study.High performance liquid chromatography(HPLC)was employed using a SymmetryShield™C18 column and a diode array detector(DAD)at 265 nm.The mobile phase consisted of acetonitrile and 0.1%acetic acid aqueous solution(pH 2.50)at a volume ratio of 18∶82.Under the optimized chromatographic conditions,picloram,clopyralid and aminopyralid in the samples were effectively separated and quantified.The results indicated that the linear correlation coefficients(R²)for picloram,clopyralid and aminopyralid were 0.999 7,0.999 9 and 0.999 7,respectively.The relative standard deviations were 0.9%,0.29%and 0.72%with the corresponding standard deviations of 0.052,0.05 and 0.044,respectively.Additionally,the average recoveries of the three active ingredients were determined to be 99.60%,99.89%and 100.36%,respectively.This established method exhibits high precision and accuracy,satisfactory chromatographic separation and good linearity,which can fully meet the technical requirements for the quantitative quality control of the target formulation.关键词
