通过对沸石滤柱吸附去除饮用水中微量邻苯二甲酸酯(又称为酞酸酯,phthalate esters,PAEs)的研究,探讨其工程应用的可行性.邻苯二甲酸二甲酯(DMP)、邻苯二甲酸二丁酯(DBP)、邻苯二甲酸二辛酯(DOP)、邻苯二甲酸二(2-乙基己基)酯(DEHP)4种PAEs被选作目标物质.控制沸石滤柱的空床接触时间为12～18 min,使DMP、DBP、DOP及DEHP 4种酯类进水浓度皆为20～100μg/L;通过高效液相色谱法(HPLC)测定出水中每种PAE的浓度.研究发现,总PAEs的去除率在24.7%～33.8%之间;随着进水浓度的增加,DMP、DBP的去除率下降,DEHP、DOP去除率上升.

The feasibility using zeolite filter column was investigated to remove phthalate esters from drinking water through a bench scale study. Dimethyl phthalate (DMP), dibutyl phthalate (DBP), dioctyl phthalate (DOP) and di-(2-ethylhcxyl) phthalate (DEHP) were selected as the representative target contaminants, and the each PAE influent concentration of the zeolite filter column is about 20μg/L～100 μg/L. The four sorts of PAE were determined with the high performance liquid chromatography(HPLC) at the condition of the zeolite filter column's empty bed contact time (EBCT) from12 min to 18 min. The results indicated that the removal efficiency of total PAEs (contain DMP, DBP, DOP and DEHP) was fluctuating within 24.7% ～33.8%; with the increase of the influent concentration, the removal rate of DMP and DBP decreased while DEHP and DOP increased.
