Abstract

     Endüstriyel atık
sulardan uçucu organik bileşenlerin giderilmesi çevre kirliliğinin önlenmesi
için oldukça önemlidir. Bu çalışmada polivinil klorür/perlit nanokompozit
filmler hazırlanarak uçucu organik bileşen metanolün pervaporasyon prosesi ile
sudan giderilmesi incelenmiştir. Hazırlanan polivinil klorür/perlit
nanokompozit filmler FTIR, TGA ve SEM ile karakterize edilmiştir. Polivinil klorür
film içindeki perlit konsantrasyonu, operasyon sıcaklığı, beslemedeki metanol
konsantrasyonu gibi parametrelerin pervaporasyon prosesi ile sudan metanolü
uzaklaştırmada etkisi incelenmiştir. Polivinil klorür/perlit nanokompozit
filmlerdeki perlit miktarı arttıkça ayırma faktörünün arttığı, geçiş hızının
ise azaldığı görülmüştür. Sıcaklık ve besleme konsantrasyonundaki artış ise
geçiş hızının artması ve ayırma faktörünün azalması ile sonuçlanmıştır.
Ağırlıkça %2 metanol besleme konsantrasyonunda, 30^oC'de, %8 perlit
konsantrasyonunda 0.16kg/m².sa akı ve 87 ayırma faktörü değeri elde
edilmiştir. Elde edilen bu değerler literatürdeki çalışmalarla kıyaslandığında
sulu çözeltilerden metanolün gideriminde PVC/perlit nanokompozit filmlerin
oldukça başarılı bir ayırma performansı sergilediğini göstermiştir.
