The objective of this paper is to investigate the effect of mixing time on removal of Cd and Pb in micellar enhanced ultrafiltration with DCA(deoxycholic acid). Permeate flux, rejection ratio of DCA, and removal efficiency of Cd and Pb were gradually increased with increase of mixing times, they had almost reached equilibrium after 1hr of mixing. The rejection ratios of DCA in Cd and Pb solution were 91.6% and 93.8%, respectively. The removal efficiencies of Cd and Pb were 99.7% and 99.9%, respectively.
