Merkapto-Fonksiyonlu Kaliks[4]aren Bazlı Polimer İçerikli Membranın Ağır Metal Taşıma Verimliliği

Bu çalışmada, bazı ağır metallerin, yeni bir membran (HS-C@PIM) kullanılarak sulu ortamdan verimli bir şekilde taşınması tasarlanmıştır. Bu amaçla; ağır metaller için uygun bir bağlanma yeri olan bir merkapto-sübstitüe kaliksaren türevi polimer içeren membranda taşıyıcı olarak kullanıldı. HS-C@PIM’in yapısını ve yüzey morfolojisini değerlendirmek için taramalı elektron mikroskopisi (SEM), Termogravimetrik analiz (TGA) ve elementel analiz teknikleri kullanıldı. HS-C@PIM’ nin Cu(II), Zn(II), Pb(II), Ni(II), Cd(II) ve Co(II) ye karşın katyon taşıma etkinliğini değerlendirmek için Donnan diyaliz yöntemi uygulanmıştır. Sonuçlar, yeni HS-C@PIM’in % 43 ile Cu(II)’ yi taşıma yapabildiğini göstermektedir
