Abstract

The aim of the experiment is to characterize the Modified Membrane from PVDF/PAN and its application in removing the Emulsified oil waste from the Industry. To get the maximum separation of the emulsified oil from the waste water, composite (PVDF/PAN) membrane was prepared in the laboratory. New PVDF/PAN blend based ultrafiltration membranes were synthesized by phase inversion method. The blend membrane was treated at room temperature with aqueous sodium hydroxide solutions. The facile eco-friendly preparation of PVDF/PAN blended membrane has a wide potential for practical applications in emulsified wastewater remediation. The chemical functionality of the modified membranes was confirmed by IR spectra. For the separation of emulsified oily wastewater, the as-prepared composite (PVDF/PAN) membrane could effectively separate oil/ water emulsions with separation efficiency of above 99.8%. Unmodified membranes (A and B) showed 95.4-99.8% rejection. However, in the case of membranes C and D, oil rejection was higher for the modified membranes as compared to the unmodified membranes.

PVDF/PAN膜分离工业废油的潜力评价

研究了聚偏氟乙烯/聚丙烯腈改性膜及其在工业废油乳化处理中的应用。为了最大限度地分离废水中的乳化油，在实验室制备了复合膜(PVDF/PAN)。采用相转化法制备了新型PVDF/PAN共混超滤膜。用氢氧化钠水溶液在室温下处理共混膜。聚偏氟乙烯/聚丙烯腈共混膜的制备工艺简便、环保，在乳化废水处理中具有广泛的应用前景。红外光谱证实了改性膜的化学功能。对于乳化含油废水的分离，所制备的复合膜(PVDF/PAN)可有效分离油水乳液，分离效率达99.8%以上。未修饰膜(A和B)的排异率为95.4-99.8%。然而，在膜C和D的情况下，与未改性的膜相比，改性膜的排油率更高。
