辛醇辅助磁固相萃取-HPLC检测环境水中酚类物质

Octanol enhanced MSPE coupled with HPLC for the determination of five phenolic compounds in environmental water

    摘要
  • 摘要: 建立了一种磁固相萃取 (MSPE) - 高效液相色谱法 (HPLC) 测定环境水样中的5种酚类化合物(双酚A、双酚AF、 四溴双酚A、辛基酚和壬基酚)的方法.利用磁性纳米材料易分散、分离速度快的特点,以辛醇和Fe3O4@壬酸磁性纳米材料为萃取剂,辛醇通过涡旋混合吸附在磁性材料上,构成Fe3O4@壬酸@辛醇体系,实现对目标物的高效、快速吸附.实验考察了影响目标物萃取效率的条件,在最佳条件下,5种酚类化合物的线性范围为 0.5~100.0μg·mL-1(R2>0.998),检出限(LODs)范围为0.07~0.16μg·mL-1(S/N=3),样品的加标回收率在88.7%~98.2%,相对标准偏差 (RSDs,n=5) 范围为2.9%~5.9%.

     

    Abstract: A simple and effective method based on octanol enhanced magnetic solid-phase extraction (MSPE) coupled with high-performance liquid chromatography (HPLC) for the determination of five phenolic compounds(BPA,BPAF,TBBPA,NP and OP)in environmental water was established.Using the characteristics of magnetic nanoparticles which are easy to disperse and fast to separate,octanol and Fe3O4@n-nonanoic acid nanoparticles were used as extractant, furthermore,octanol was used to coat n-nonanoic acid Fe3O4 nanoparticles with core-shell structures to prepare MSPE agents (Fe3O4@n-nonanoic acid @octanol).The main parameters affecting the extraction efficiency of five phenolic compounds were studied. Under optimal conditions,the calibration curves were linear in the range of 0.5—100μg·mL-1 (R2>0.998) of five phenolic compounds.The limit of detections (LODs) and relative standard deviations (RSDs,n=5) of the method were 0.07—0.16μg·mL-1 and 2.9%—5.9%,respectively.The adding standard recoveny of the sanple is 88.7%—98.2%.
