液液萃取/气相色谱-质谱法同时测定污水中12种邻苯二甲酸酯类化合物
Simultaneous Determination of 12 Phthalate Esters in Wastewater via Liquid-Liquid Extraction/Gas Chromatography-Mass Spectrometry
摘要
Abstract
In this study,a method for simultaneous determination of 12 phthalate esters(PAEs)in wastewater using gas chromatography-mass spectrometry(GC-MS)was established.For each sam-ple,100 mg/L of ascorbic acid was added to reduce matrix interference;then,liquid-liquid extrac-tion was performed using n-hexane(n-hexane∶sample=250∶1,volume ratio).The n-hexane ex-tract was determined via GC-MS and quantified using the internal standard method.The results re-vealed good linearity for the 12 PAEs in the concentration range of 10 to 1 000 μg/L,with correlation coefficients(r2)＞0.99.The limits of detection and limits of quantification were in the ranges of 0.004 to 0.068 μg/L and 0.013 to 0.227 μg/L,respectively.The average spiked recoveries ranged from 79.5％to 122％,and the relative standard deviations were between 0.23％and 19％;these results in-dicate that the proposed method has good accuracy and stability.This method was used to determine PAEs in real influent samples from five wastewater treatment plants in the Pearl River Delta,where each plant employs different treatment processes.In addition to the common phthalates such as diiso-butyl phthalate,dibutyl phthalate,and bis(2-ethylhexyl)phthalate,dioctyl phthalate was also de-tected.Thus,the proposed method is suitable for the accurate analysis and determination of trace PAEs in real wastewater samples.关键词
