采用固相萃取法对水样进行提取富集，气相色谱法测定水中6种邻苯二甲酸酯类有机污染物，并对方法进行了探索、优化和验证。对水体pH在固相萃取过程中对邻苯二甲酸酯萃取回收率的影响进行了研究，解决了邻苯二甲酸2-乙基己基酯和邻苯二甲酸二正辛酯回收率不高的问题。在空白水加标实验中，邻苯二甲酸酯的回收率能达到93.2％～116.3％。除此之外，还对工业废水和地表水进行了加标回收实验，获得了较高的回收率及测定精度。

The development, optimisation and validation of a method for the determination of trace levels of phthalate esters in aqueous media is described. Extraction is by solid phase extraction followed by GC analysis. By adjusting the pH to the sample before the SPE, the recovery may be improved when di-(2-ethylhexyl) phthalate ( DEHP) and di-n-octylphthalate ( DnOP) determination is required. The accuracy determined as recovery was 93.2%-116.3% for both compounds in distilled water. In addition, recoveries and method precision of phthalates were measured in wastewater and surface water.
