Abstract：

Viscous oil separation and its highly efficient recovery is a great challenge in oil/water separation fields. Among the many oil/water separation methods, membrane separation is considered to be one of the most forward-looking strategies, but membrane fouling caused by oil droplets severely limits its application. We here propose a nondispersive solvent extraction strategy to efficiently recover viscous lubricant oil from emulsions via a polydopamine modified PVDF nanofiber membrane Janus membrane. The incorporated thin polydopamine layer facilitates the adsorption and diffusion of surfactant stabilized oil droplets through the membrane. We studied the influence of polydopamine coating time, the flow rate on both feed and extraction sides, the weight content of lubricant oil on the recovery and separation of oil. The optimized membrane exhibited a 10 h accumulative flux of 1595 g/m2 for viscous lubricant oil in water emulsion, which was twofold higher than the pristine PVDF nanofiber membrane. The current study might significantly advance application of this novel method for highly efficient separation and recovery of viscous oils from oil/water mixtures.
