In this study, two novel supported liquid membranes (SLMs) was developed by using Trioctylphosphine oxide (TOPO) and N-(furane-2-iylmethyl)-N’-hydroxy-2-oxo-2-(4-phenylphenyl) eteneimideamide (BKOF) as a carrier that have different functional groups, each dissolved in the organic phase N-N-dimethyl formamide. Hydrophobic polyvinylidene fluoride (PVDF) and polyamide microporous membranes were used as support to prepare these membranes. Developed membranes were characterized with several analytical methods, including scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (SEM-EDS), Fourier transform infrared spectroscopy (FTIR), atomic force microscopy (AFM), and thermal gravimetric analysis (TGA). Characterization processes confirm the novelty of membranes due to different surface morphologies of prepared SLMs, compared to the PVDF and polyamide supports. Performance of prepared SLMs were evaluated by rejection tests for Ni(II) and Fe(III)) from aqueous solutions by using Donnan dialysis method. The highest flux values were obtained when the feed phase concentration of 1.0x10^-1 M NiCl₂.6H₂O or 1.0x10^-1 M Fe(NO₃)₃.9H₂O, the strip phase concentration of 1.0x10^-1 M HCl or 1.0x10^-1 M HNO₃, respectively.

Bu çalışmada, taşıyıcı olarak farklı fonksiyonel gruplara sahip ve her biri N-N- dimetil formamit organik fazında çözünen trioktilfosfin oksit (TOPO) ve N-(furan-2-ilmetil)-N’-hidroksi-2-okso-2-(4-fenilfenil)-etenimidamit (BKOF) bileşikleri kullanılarak iki yeni tür destekli sıvı membran (DSM) hazırlanmıştır. Destek tabakası olarak hidrofobik poliviniliden florür (PVDF) ve poliamit mikroporöz membranlar kullanılmıştır. Hazırlanan membranlar taramalı elektron mikroskobu (SEM), enerji dağılım X-ray spektroskopisi (SEM-EDS), atomik güç mikroskobu (AFM), fourier dönüşümlü infrared spektroskopisi (FTIR) ve termogravimetrik analiz (TGA) gibi analitik metotlar kullanılarak karakterize edilmiştir. Karakterizasyon işlemleri, hazırlanan DSM’lerin yüzey morfolojilerinin PVDF ve poliamit destek tabakalarına kıyasla farklı olması, bu membranların yeni tür olduklarını doğrulamaktadır. Hazırlanan DSM’lerin performası, donnan diyaliz metodu kullanılarak sulu çözelti ortamından Ni(II) ve Fe(III) iyonlarının uzaklaştırma deneylerinde değerlendirilmiştir. En yüksek akı değerleri besleme fazı konsantrasyonu 1,0x10^-1 M NiCl₂^.6H₂O veya 1,0x10^-1 M Fe(NO₃)₃.9H₂O ve alıcı faz konsantrasyonları 1,0x10^-1 M HCl veya 1,0x10^-1 M HNO₃ olduğu zaman elde edilmiştir.
