  • Several factors such as temperature, pH, initial concentration, transmembrane pressure (TMP) and running time which affect membrane flux and retention efficiencies were investigated by using DL1210 nanofiltration membrane to remove dibutyl phthalate (DBP), phthalate, bis (2-ethylhexyl) ester (DEHP), dimethoate and atrazine. The results showed that the nanofiltration process is an effective method to remove traces DBP, DEHP, dimethoate and atrazine. The retention efficiencies of nanofiltration membrane on DBP, DEHP, dimethoate and atrazine decreased with an increase in pH and temperature. And the membrane retention efficiencies on DBP and DEHP also decreased with an increase in initial concentration. However, TMP and running time have no significant impact on the membrane flux and the retention efficiencies of target pollutants. Finally, The nanofiltration process achieved the best retention efficiencies on DBP, DEHP, dimethoate and atrazine under the condition of the initial pH of 5, the initial concentration of 5 μg/L, a temperature of 5℃ and TMP of 0.4 MPa with retention efficiencies of 91.8%, 89.8%, 98.02% and 77.6%, respectively. And the effluent concentrations of DBP, DEHP, dimethoate and atrazine were 0.41, 0.49, 0.099 and 1.12 μg/L, respectively.
