| 摘 要： | 用反相离子对色谱测定五氟苯甲酸,采用Shimpack C18色谱柱(150 mm×6 mm,5μm),流动相:甲醇-0.02 mol/L四丁基氢氧化铵(体积比7∶3),pH=2.5(H3PO4)。流速1 mL/min,柱温25℃,检测波长268nm。测定五氟苯甲酸的线性范围为16.61~415.2 mg/L,回归方程为y=8 584x+94.93,r=0.998 1(n=7),平均加标回收率98.8%。相对标准方差为1.46%(n=6)。

| Abstract: | A reversed-phase ion pair chromatography method for the determination of pentafluorobenzoic was developed.The Simpack C_(18)(150 mm×6 mm,15 μm)column was used.The mixture of methanol and(0.02) mol/L tetabutylammonium hydroxide(7∶3) was used as the mobile phase with flow rate of 1.0 mL/min.The column temperature was 25 ℃ and detection wavelength was set at 268 nm.A good linear relationship between the peak area and the quantity of pentafluorobenzoic in the rang from 16.61 g/L to 415.2 g/L with the regression equation y=8 584x+94.93 and r=0.998 1(n=7) was obtained.The recovery was 98.8% and RSD was 0.47%(n=6). |
