a Schematic illustration of the selective separation of oil/water mixtures. PCRM means potato residue coated-mesh. b Separation of kerosene–water mixtures (where ρwater > ρoil). c Separation of chloroform–water mixtures (where ρwater < ρoil) (the water was dyed with methylene blue and oil is dyed with Oil Red O to enhance the visual effect) [84]
