title: [Researches on factors affecting the removal of carbamazepine by nanofiltration membranes].
abstract: The influence factors on removal of carbamazepine (CBZ) in drinking water by nanofiltration membrane was mainly investigated. The effect of CBZ removal by NF270 and NF90 was firstly compared and found that removal efficiency by NF90 with small pore size showed more effectively than removed by NF270 with large pore size. The next experiment focused on the effect of various factors on removal with respect to CBZ initial concentration, pH, ionic strength and water temperature. The results showed that removal efficiency reduced with decreased pH and increased Ca2+ concentration and water temperature. The effect of initial concentration in the range of 50-500 microg/L on flux and CBZ removal was insignificant. It can be concluded that the retention of non-ionic CBZ by loose NF membrane was strongly dependent on the mechanism of steric (size) exclusion.
