Purification of Emulsified Oil by Polyvinylidene Fluoride/Polyvinyl Pyrrolidone Membrane

Abstract

In this study, polyvinyl fluoride (PVDF) and polyvinylpyrrolidone (PVP) based adsorbent membranes containing Bentonite clay were developed and used for selective separation of oils from oily wastewater. This membrane selectively separates emulsified oils from water when used as adsorbents. The affinity of membranes in different types of oil and water was determined by swelling tests in oil and water. Membrane morphology was determined by scanning electron tests and the bond structure was determined by Fourier Infrared Spectroscopy. As a result, it was observed that gteater than 200% of oil absorptionwas obtained when the membrane immersed in soybean oil and hazelnut oil and greater than50% of oil absorption was achieved when the membrane immersed in toluene. Filtration test of the same membranes gave the oil rejection values between 65% and 99%. Consequently, it was evaluated that Bentonite incorporation increased the flux value. However, oil rejectionwas negatively affected from the Bentonite incorporation.In the case of toluene, rejection value of 99.9% was achieved when Bentonite amount was 15.%.

Emülsifiye Edilmiş Yağın Polivinil Florür/Polivinil Prolidon Membran İle Saflaştırılması

Abstract

Bu çalışmada, Bentonit kili içeren polivinilflorür (PVDF) ve polivinilprolidin (PVP) bazlı adsorban membran geliştirilerek yağlı atık sulardan yağların seçici olarak ayrılması için kullanılmıştır. Bu membran adsorban olarak kullanıldığında emülsifiye edilmiş yağları sudan seçiçi olarak ayırmaktadır. Membranın farklı yağ türlerine ve suya olan ilgisi, yağ ve su içindeki şişme testleriyle belirlenmiştir. Membran morfolojisi taramalı elektron testleri ile bağ yapısı Fourier Dönüşümlü Kızılötesi Spektroskopisi ile belirlenmiştir. Sonuç olarak membranların soya yağı, fındık yağı içine daldırıldığında %200 ‘den fazla, toluene daldırıldığında 50’den fazla yağ emilimi sağladığı görülmüştür. Aynı membranların filtrasyon testi sonucunda %65 ile %99 arasında yağ reddetme değerleri elde edilmiştir. Membrana eklenen Bentonitin akı değerini arttırdığı ancak soya ve fındık yağ reddini azalttığı görülmüştür. Toluen reddinin ise Bentonit katkısından çok fazla etkilenmediği görülmüştür.%15 Bentonit katkılı membranın toluen reddi değerleri %99.9 olarak elde edilmiştir.
