Abstract

Polyethylene Terephthalate (PET) bottle is used as beverage packaging, which is very convenient as one time use packaging. However, the huge amount of PET bottle waste has been becoming a serious problem for the environment. The utilization of PET bottle waste is very important to reduce the environmental problem. In this work, PET bottle waste was used a raw material to develop an ultrafiltration (UF) membrane. The membrane was prepared by using a phase inversion technique. The effect of the type of solvent, additive, and non-solvent on the microstructure and ultrafiltration performance of the membrane was studied. Different type of solvent, phenol, m-cresol, and DMSO were used to dissolve PET bottle as the source of membrane polymer. Two different additives, Polyethylene Glycol (PEG) and Polyvinyl Pyrrolidone (PVP) were used. Membrane 3 with the composition of PET, phenol as solvent, and PEG as additive was prepared successfully. The variation of aqueous alcohol solutions as non-solvent resulted in different microstructures of the membranes as shown by the scanning electron microscopy (SEM). The permeation experiment result using pure water as the feed showed that membrane 3 using aqueous butanol as non-solvent (membrane 3-ButOH) exhibited the highest permeate flux compared to that of membrane 3 using aqueous propanol (membrane 3-PrOH) or ethanol as non-solvent (membrane 3-EtOH). The ultrafiltration experiment was carried out using a feed solution of water containing polyethylene glycol (PEG) 20,000. The membrane 3-EtOH showed the lowest permeate flux of 3.24 kg/m h, but the highest rejection of PEG 20,000 of 65.87%. The membrane 3-PrOH had a permeate flux of 11.57 kg/m h and a rejection of 64.73%. Whereas the membrane 3-ButOH showed the highest permeate flux of 27.78 kg/m h, but the lowest rejection 16.93%. This result was obtained due to the different membrane microstructures which were strongly affected by the type of non-solvent.

聚对苯二甲酸乙二醇酯(Pet)瓶废液超滤膜的研制

聚对苯二甲酸乙二醇酯(PET)瓶作为饮料包装，作为一次性使用包装非常方便。然而，大量的PET瓶废弃物已经成为一个严重的环境问题。PET瓶废弃物的资源化利用对减少环境问题具有重要意义。本研究以PET瓶废料为原料，制备超滤膜。采用相转化技术制备了该膜。研究了溶剂类型、添加剂和非溶剂对膜的微观结构和超滤性能的影响。采用不同类型的溶剂，苯酚、间甲酚和二甲二甲砜作为膜聚合物的来源，对PET瓶进行溶解。使用了两种不同的添加剂，聚乙二醇(PEG)和聚乙烯吡咯烷酮(PVP)。成功制备了以PET、苯酚为溶剂、PEG为添加剂的膜3。扫描电子显微镜(SEM)显示，乙醇水溶液作为非溶剂的变化导致膜的微观结构不同。以纯水为进料的渗透实验结果表明，以丁醇为非溶剂的3号膜(3- butoh膜)比以丙醇为非溶剂的3号膜(3- proh膜)和乙醇为非溶剂的3号膜(3- etoh膜)的渗透通量最高。采用含聚乙二醇(PEG) 20000的给水溶液进行超滤实验。3-EtOH膜的渗透通量最低，为3.24 kg/m h，但对PEG 20000的截除率最高，为65.87%。3-PrOH膜的渗透通量为11.57 kg/m h，去除率为64.73%。3-ButOH膜的渗透通量最高，为27.78 kg/m h，截留率最低，为16.93%。这是由于不同的膜微观结构受到非溶剂类型的强烈影响。
