建立了以固相萃取技术进行富集，高效液相色谱法进行分离和检测苯氧乙酸和2，4-二氯苯氧乙酸的方法。环境水中的苯氧乙酸和2,4-二氯苯氧乙酸用Sep-Pak C18 Cartridge进行固相萃取。液相色谱的条件是：Shim-Pack CLC ODS柱为分析柱；甲醇-水(9:1,V/V)为流动相；流速为1mL/min；在UV-275nm波长下进行检测。本法具有良好的灵敏度和重现性。

A high performance liquid chromatographic method for the determination of phenoxyacetic acid and 2,4-dichlorophroxyacetic acid in environnmental waters was described.Phenoxyacetic acid and 2, 4-dichioropheroxyacetic acid in sample were enriched on Sep-Pak C18 column,and methanol was employed as elutent.The shim-pack CLC ODS (150mm×6.0mm i.d.) column was used as separation column at 40°C and eluted with methanol-water (9:1,V/V)(pH 3.0) at flow rate of 1.0mL/min,the detection wavelength was 275 nm.The recoveries of the two compounds were＞98%.The detection limit was 0.04mg/L.
