| Abstract: | The phase inversion technique was used for synthesis anthracene molecularly imprinted membrane (An–MIM) by hybridizing anthracene molecularly imprinted nanoparticles polymer (An–MINP) with cellulose acetate (CA). An–MIM gives high binding capacities toward anthracene, naphthalene, pyrene, benzo(a)pyrene, phenanthrene, and acenaphthylene. Meanwhile, cellulose acetate membrane (CAM) and none imprinted membrane give very low binding capacities toward Anthracene, Naphthalene, Pyrene, Benzo(a)pyrene, Phenanthrene and Acenaphthylene. The separation properties of An–MIM, none imprinted membrane (NIM), and CAM were investigated in terms of selectivity, rejection percentages, and concentrating factor. The optimum operation time of An–MIM was found to be 3 hr. The overall results indicated that the presence of chemical binding sites in the An–MIM plays predominating role in the separation properties. Therefore, An–MIM proved to be highly efficient for the removal of polycyclic aromatic hydrocarbons at various percentages. Copyright © 2015 John Wiley & Sons, Ltd. |
