- Abstract
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.
