A porous ceramic tube with superhydrophobic and superoleophilic surface was fabricated by sol-gel and then surface modification with polyurethane-polydimethysiloxane, and an oil-water separator based on the porous ceramic tube was erected to characterize superhydrophobic and superoleophilic surface's separation efficiency and velocity when being used to reclaim oil from oily water and complex oily water containing clay particle. The separator is fit for reclaiming oil from oily water.
Graphical abstractPorous ceramic membrane with superhydrophobic and superoleophilic surface used to reclaiming oily from oily water containing clay particles.Download full-size imageHighlights⺠Porous ceramic membrane with superhydrophobic and superoleophilic inner surface has been fabricated via sol-gel method and then surface modification with a low surface energy coating. ⺠An oil- water separator based on the membrane can reclaim directly oil from oily water or even from oily water containing clay particles. ⺠The Separation efficiency and velocity depend on oil content of oily water and whether contains clay particles.
