Poliakrilonitril-ko-poli(2-etilhegzil akrilat) Kopolimerleri İle Narinjin Filtrasyonu

Öz

Farklı akrilonitril/2-etilhegzil akrilat oranlarına sahip poliakrilonitril-ko-poli(2-etilhegzil akrilat) kopolimerleri sentezlenmiş ve narinjin filtrasyonu performansları test edilmiştir. Akış hızı kopolimer zardaki poli(2-etilhegzil akrilat) miktarıyla artmıştır. Filtrasyon performansı ise kopolimer zardaki artan poliakrilonitril miktarıyla artmıştır. Narinjinin yüzde filtrasyon değerleri PAN(84)-ko-P2EHA(16), PAN(88)-ko-P2EHA(12) ve PAN(92)-ko-P2EHA(8) kopolimerleri için sırasıyla %53.5, %74.9 ve %92.6 olarak bulunmuştur. Ayrıca kopolimer zarlar beşinci kullanımdan sonra başlangıç performanslarının %83’ünü korumuşlardır.

Naringine Filtration By Polyacrylonitrile-co-poly(2-ethylhexyl acrylate) Copolymers

Öz

Polyacrylonitrile-co-poly(2-ethylhexyl acrylate) copolymers with different acrylonitrile/2-ethylhexyl acrylate ratios were synthesized and tested in terms of filtration performance for naringine removal. The flux increased with poly(2-ethylhexyl acrylate) content of the copolymer membrane. Moreover, the filtration performance increased with increasing polyacrylonitrile content of the copolymer membrane. The percent removal of naringin was found as 53.5%, 74.9% and 92.6% for PAN(84)-co-P2EHA(16), PAN(88)-co-P2EHA(12) and PAN(92)-co-P2EHA(8), respectively. Also, copolymer membranes could preserve its 83% of its initial performance after the fifth use.
