Karbon nanotüpler (CNT) olağanüstü eşsiz özellikleri sebebiyle keşfinden günümüze birçok uygulama alanı bulmuştur. Yüzeylerinde gerçekleştirilen kovalent modifikasyonlarla kimyasal ve fiziksel özellikleri geliştirilebilmektedir. Bu çalışma ile 1-aza-18-crown-6 modifiye karbon nanotüpler Steglich esterleşmesi ile sentezlenmiştir. Sentezlenen bileşik FTIR, 1H-NMR, 13C-NMR, TGA ve TEM yöntemleriyle karakterize edilmiştir. Elde edilen bileşiğin ve modifiye edilmemiş CNT bileşiğinin Fe3+, Mn2+, Co2+, Cr3+, Cu2+, Zn2+ metal iyonlarını adsobsiyonu incelenmiştir. Adsorpsiyon yüzdesi (% A.Y.), adsorpsiyon kapasitesi (qe), maksimum adsorpsiyon kapasitesi (qmax), adsorpsiyon denge sabiti (Kd), Serbest Gibbs Enerjisi (ΔGo) ve izoterm türü belirlenmiştir. Adsorpsiyon çalışmalarına göre, monoaza-18-crown-6 modifiye edilmiş çok duvarlı karbon nanotüp (MWCNT-CO-(MA-18-Crown-6)) bileşiği, tüm metal iyonlarını ham çok duvarlı karbon nanotüpten (MWCNT) çok daha iyi yüzdelerde adsorbe ettiği gözlenmiştir. MWCNT-CO-(MA-18-Crown-6) bileşiği, çözelti içindeki Fe3+ iyonlarının yaklaşık olarak tamamını (% 96.15) adsorbe etmiştir. Bu sonuçlar ışığında elde edilen MWCNT-CO-(MA-18-Crown-6) bileşiği metal iyonlarının sulu ortamlardan adsorpsiyonunda başarılı bir şekilde uygulanabileceği söylenebilir.

Carbon nanotubes (CNT) have found many applications since their discovery due to their extraordinary unique properties. Its chemical and physical properties can be improved by covalent modifications on its surfaces. In this study, 1-aza-18-crown-6 modified carbon nanotubes were synthesized by Steglich esterification. The synthesized compound was characterized by FTIR, 1H-NMR, 13C-NMR, TGA and TEM methods. The adsorption of Fe3+, Mn2+, Co2+, Cr3+, Cu2+, Zn2+ metal ions of the obtained compound and unmodified CNT compound was investigated. Adsorption percentage (A.Y.%), adsorption capacity (qe), maximum adsorption capacity (qmax), adsorption equilibrium constant (Kd), Free Gibbs Energy (ΔGo) and isotherm type were determined. According to adsorption studies, for the monoaza-18-crown-6 modified multi-walled carbon nanotube (MWCNT-CO-(MA-18-Crown-6)) compound has adsorbed all metal ions much better percentages than crude multi-walled carbon nanotube (MWCNT). MWCNT-CO-(MA-18-Crown-6) compound has adsorbed approximately all of the Fe3+ ions in solution (96.15%). In the light of these results, it can be said that the MWCNT-CO-(MA-18-Crown-6) compound can be successfully applied in the adsorption of metal ions from aqueous environments.
