Bu çalışmada, biyobozunur polilaktik asit polimerinin yağ-su ayırımındaki performansı incelenmiştir. Çalışma kapsamında membranlar hazırlanmış ve vakum filtrasyon işlemi uygulanmıştır. Membranın yağ ve suya olan ilgisi, yağ ve su içindeki şişme testleriyle belirlenmiştir. Membranın hidrofilitesini arttırmak ve performansını iyileştirmek için içine halosit nanotüp (HNT) eklenmiş ve nanokompozit haline getirilmiştir. Membranın yüzey morfolojisi taramalı elektron mikroskobuyla (SEM) ile belirlenmiştir. Çalışmada halosit nanotüp oranının (%0-20), yağ/su şişme oranlarına (adsorpsiyon oranına), membrandan geçen sıvı akısına ve yağ reddine etkisi belirlenmiştir. Çalışmada model yağ olarak soya yağı seçilmiştir. Soya yağı-su emülsiyonu hazırlanarak ayırım testleri yapılmıştır. Elde edilen sonuçlara göre soya yağı ayırımında %5 HNT katkısında %97.2 saflıkta su alt akımdan elde edilmiştir. Yüksek ayırımın yanında 1714.3 üzerinde saatte litre bazında su akısı elde edilmiştir.

Oily water separation by using biocomposite membrane

Öz

In this study, the performance of biodegradable polylactic acid polymer in oil-water separation was investigated. Within the scope of the study, membranes were prepared and vacuum filtration process was applied. The affinity of the membrane for oil and water was determined by swelling tests in oil and water.In order to increase the hydrophilicity of the membrane and improve its performance, haloside nanotube (HNT) was added and turned into nanocomposite. The surface morphology of the membrane was determined by scanning electron microscopy (SEM). In the study, the effects of halocyte nanotube ratio (0-20%) on oil/water swelling ratios (adsorption ratio), fluid flux through the membrane and oil rejection were determined. Soybean oil was chosen as the model oil in the study. Separation tests were carried out by preparing soybean oil-water emulsion. According to the results obtained, 97.2% pure water was obtained from the bottom stream with the addition of 5% HNT by weight in the soybean oil separation. Besides the high separation, the water flow on the basis of liters per hour was obtained over 1714.3 LMH.
