摘要
建立了液液萃取、氧化铝-硅胶柱净化分离、GC-MS内标法测定水样中12种OPEs含量的方法。12种OPEs标准曲线的相关系数R在0. 9872~0. 9995之间,仪器检出限为0. 08~29. 6 pg,方法检出限为0. 10~6. 43 ng/g。在加标空白样品中,12种OPEs的回收率为57. 4%~109. 7%。应用该方法测定广州市中心六区12个采样点的自来水样品,OPEs含量为0. 183~0. 423μg/L,其中TBP含量最高,其次为TBEP、TCEP、TCPP、TDCP。市售瓶装水OPEs含量为0. 017~0. 038μg/L,含量均较低,说明市售的瓶装水基本未受OPEs污染。
A method for the determination of 12 kinds of OPEs in water samples by liquid-liquid extraction,aluminasilica gel column purification and separation and GC-MS internal standard was developed. The correlation coefficients of12 OPEs were between 0. 9872 and 0. 9995,the detection limit of the instrument was between 0. 08 and 29. 6 pg,and the detection limit of the method was between 0. 10 and 6. 43 ng/g. In the blank samples,the recovery rate of the 12 OPEs was57. 4% to 109. 7%. The contents of OPEs were 0. 183 ~ 0. 423 μg/L in tap water samples collected from 12 sampling sites in6 districts of Guangzhou city. TBP content was the highest,followed by TBEP,TCEP,TCPP and TDCP. The content of OPEs in bottled water was 0. 017 ~ 0. 038 μg/L,which indicated that the bottled water was not polluted by OPEs.
