Abstract
Bu çalışmada, daha önceden sentezlenmiş olan 4-(4-{4-[1-metil-3-oksobutilidenamino] fenil} fenilimino)-2-pentanon (BAA) schiff bazı kullanılarak farklı destek tabakaları ve farklı çözücüler ile destekli sıvı membranlar hazırlanmıştır. Donnan diyaliz yöntemi ile sulu ortamda belli bir miktarı aşması durumunda zararlı olabilecek Cu(II) katyonunun seçimli olarak ayrılması ve taşınması özellikleri bu yeni hazırlanan membranlar kullanılarak incelenmiştir. Bu membranlar kullanılarak konsantrasyon etkisinin Cu(II) iyonunun taşınmasındaki etkisi incelenmiş ve Cu(II) için akış (J) değerleri hesaplanmıştır. Metal iyonlarının akışı, konsantrasyon artışı ile artmıştır. Hazırlanan bu yeni tip membranların karakterizasyon işlemleri SEM, AFM ve FTIR ile yapılmıştır. Farklı membranlarda farklı akış olması membran yapılarının farklılığı ile açıklanmıştır. Hazırlanan membranların kalınlıkları da belirlenmiştir. Ayrıca, membranların potansiyel ölçüm deneyleri de incelenmiştir.
