  • 摘要: 分别以l-辛基-3-甲基咪唑六氟磷酸离子液体([C8MIM][PF6])和三辛基氧化膦(TOPO)作为萃取剂与辅助萃取剂,建立了中空纤维膜辅助的两相液液微萃取-高效液相色谱测定环境水体中水杨酸(Salicylic acid,SA)的新方法.通过对中空纤维膜种类、萃取剂、供体相体积、供体相pH、离子强度和萃取时间相关参数进行优化,获得了较高的富集倍数(1653倍).方法的检出限为0.1 μg·L-1,线性范围为0.5—1000 μg·L-1.方法对实际样品的加标回收率为89.6%—102.4%,可应用于环境水体中痕量SA的测定.
    Abstract: Salicylic acid (2-hydroxybenzoic acid, SA) is one of emerging environmental contaminants, which could cause potential ecological risks and impact on human health. So it is necessary to develop an appropriate analytical method to detect the compound in environmental waters. In this study, using ionic liquid (1-octyl-3-methylimidazolium hexafluorophosphate, [C8MIM][PF6]) as an extracting agent and tri-n-octylphosphineoxide (TOPO) as an additive, hollow fiber membrane-based liquid phase microextraction combined with high-performance liquid chromatography was developed for the determination of SA in environmental water. Parameters that could influence the extraction performance were optimized,including hollow fiber membrane, species and volume of extraction solvent, sample pH and salinity, as well as extraction time. The developed method offered high enrichment factor (1653), low detection limit (0.1 μg·L-1, RSD=8.4%, n=6) and good linear range (0.5—1000 μg·L-1). The proposed method was applied to determine SA in a variety of environmental waters, and satisfactory recoveries (89.6%—102.4%) were obtained, indicating that the proposed method is a reliable sample pre-treatment procedure that can be applied to determining SA in aquatic environment.
