A comparative study was made of the chromatographic behaviour of five haloacetic acids (mono-, dibromoacetic and mono-, di-, trichloroacetic acids). The techniques investigated included reversed-phase ion interaction chromatography with UV detection, suppressed and non-suppressed anion-exchange chromatography. The systems are discussed studying the retention as a function of the mobile phase parameters and the stationary phases used (LiChrospher 100 RP-18, IonPac AS9, AS10 and AS11). A preconcentration step, performed on different substrates, namely LiChrolut-EN and activated vegetal carbon, has been optimized in order to reduce the method detection limits. Results obtained for drinking water samples are shown.
对五种卤乙酸(一溴乙酸、二溴乙酸、一氯乙酸、二氯乙酸和三氯乙酸)的色谱行为进行了比较研究。所研究的技术包括带紫外检测的反相离子相互作用色谱法、抑制型和非抑制型阴离子交换色谱法。通过研究保留时间与流动相参数及所用固定相(LiChrospher 100 RP - 18、IonPac AS9、AS10和AS11)的函数关系来讨论这些体系。为降低方法检测限,对在不同基质(即LiChrolut - EN和活性植物炭)上进行的预浓缩步骤进行了优化。展示了饮用水样品的检测结果。
