| الوصف: |
In ultrafiltration (UF), a pressure-driven separation process, small molecules are able to permeate through a microporous membrane, while solute molecules of high molecular weight (MW), or with markedly different polarity from the membrane, are retained in the feed stream. Cellulose acetate (CA) membranes were prepared from acetylated bacterial cellulose (nata de coco) and N,N-dimethylformamide and their permselectivity characteristics were determined using standard proteins of known MW values. The prepared CA membranes were used in separating volatile organic compounds (VOCs) from mango puree and processing effluent by means of either stirred-cell (dead-end) or tangential-flow setups. The VOCs of the permeate, retentate and feed samples were analyzed through purge-and-trap gas chromatography (PT-GC) and then through mass spectrometry (MS). The major VOCs identified and quantified through PT-GC-MS were terpinolene, 3-carene, limonene and 1-isopropyl-4-methylbenzene. Membrane rejection values of these compounds during tangential-flow UF were greater than 84% when membranes prepared from 25% CA were used. |
