表面活性剂稳定乳化油水体系的膜分离研究进展
Advances in membrane separation of surfactant-stabilized emulsified oil-water systems
摘要
Abstract
Oily wastewater often forms stable emulsions due to the presence of surfactants,making its separation challenging.Membrane separation technology has emerged as a research hotspot for addressing this challenge owing to its high efficiency and environmental benefits.This review focused on surfactant-stabilized oil-water emulsions,elucidating their separation mechanisms and separation methods.The recent advances in key membrane materials including superhydrophobic-underwater superoleophilic membranes,superhydrophilic-underwater superoleophobic membranes,under-liquid superamphiphobic membranes,stimuli-responsive membranes and Janus membranes were reviewed.Surfactants significantly reduced the oil-water interfacial tension,dispersing oil into fine and highly stable droplets.Surfactant molecules could directly adsorb onto the membrane material surface through hydrophobic interactions,electrostatic interactions or hydrogen bonding.When reaching a certain concentration,they deposited on the membrane surface,directly causing or exacerbating membrane fouling.During membrane filtration,retained substances accumulated at the membrane surface,forming a concentration polarization layer.Surfactants became highly enriched within this polarization layer,reaching concentrations potentially far exceeding those in the bulk solution,thereby further aggravating membrane fouling.Future research necessitated the targeted design and development of novel membrane materials with superior surfactant tolerance.关键词
