Removal of Polycyclic Aromatic Hydrocarbons by the Membrane Improved with Cyclodeztrine
The blend membranes of Poly(vinylidene fluoride) (PVDF), Polymethylmethacrylate (PMMA), and β-cyclodextrine (β-CD) were prepared by the phase inversion method, and their properties were investigated. The removal of four aromatic compounds (pyrene, acenaphthene, anthracene, and aniline) dissolved in water by prepared membranes was investigated. The experimental results showed that PVDF/PMMA/β-CD membranes exhibited a better pollutant removal potential compared to those without adding β-CD for polycyclic aromatic compounds (PAHs). From the images of scanning electron microscope, it was certificated that β-CD modified the morphology of membrane by increasing the dense of the pores and decreasing the pore size. The PVDF/PMMA/β-CD blend membrane has the potential to provide a higher efficiency at high permeation and retention rates and is applicable for biorefractory PAHs.
