摘要:
以中空纤维膜液相微萃取方法从水体样品中萃取了4种酞酸酯类化合物,结合气相色谱对样品进行分析.萃取中采用甲苯为萃取剂,被萃取溶液中磁子的搅拌速度为600 r/m in或更高,萃取的时间为50 m in.根据测定的结果推算出该条件之下的液相微萃取的富集倍数是19.8~221.同时确定了该方法测定酞酸酯的线性范围为10~200μg/L,检出限是0.07~0.81μg/L,用RSD表示的重现性是6.8%~9.3%,回收率为92%~106.9%.将此方法应用于取自某湖泊、某河流等体系的水样,结果表明:湖水样品中酞酸二乙酯与酞酸二丁酯分别为10.2 和9.5 μ g /L.
Abstract:
4 k inds of phthalic esters w ere extracted by using ho llow fiberm embrane liquidm icroex traction and the ir samp les were ana lyzed by com bin ingw ith gas chrom atography. The ex traction solven tw as to luene, and the stirrer speed w as 600 r /m in orm ore, and the ex traction time was 50m in. The en richm ent factor ca lcu la ted according to ana lys is results rang ed from 19.8~ 221. The linear range for the de term ination o f PAEs w as 10~ 200μ g /L. The lim its o f detec tion were 0.07~ 0.81 μ g /L. The RSD of the determ ination was 6.8% ~ 9.3%. The recove ries w ere in the range of 92% ~ 106.9%. Th is me thod w as app lied to different wa ters. The resu lts show ed that the concentration of DEP in the lake sam plew as 9.2μ g /L, 6.4 μ g /L o f DHEP in the river sam ple and the concentrations o f DEP and DBP w ere 10.2 μg /L and 9.5 μ g /L respective ly in the sam ple from the campus pond wa ter
