Abstract: |
|
The adsorption and retention of di-2-ethylohexyle phthalate (DEHP), in different water matrices (Milli-Q water, simulated water and river water) by nanofiltration (NF) was examined using two types of nanofiltration membranes (NF90 and NF70). The results showed that DEHP at a concentration of 100 μg/L could be effectively removed by the NF90, and the retention was more than 95%, and the adsorption was about 40% at filtering initial phase. Adsorption of DEHP on membranes was related to operation pressure, pH,coexisting organic and inorganic compounds, and membrane pore size. But no significant effect of DEHP concentration was observed. |
