Abstract

In this study, a new multi-walled carbon nanotube(MWCNT) based hybrid material was obtained and used as adsorbent for the removal of Cu(II) and Co(II) from aqueous solutions. In the synthesis, firstly, the surface of MWCNT was modified via Hummer method to give oxidized MWCNT-O. In the following step, the oxidized MWCNT was treated with 3-aminopropyl triethoxysilane (APTES) to give a silanized form of MWCNT having free amine end groups. Finally, the silanized MWCNT was reacted with 3, 5-dichlorosalicylaldehyde to give the hybrid material. The new hybrid material was characterized by analytical and spectroscopic methods (FT-IR, UV-Vis., TGA, Raman Spectra, SEM, TEM, EDX and XRD studies). The hybrid material was used as adsorbent for the removal of Cu(II) and Co(II) ions from aqueous solutions. The effects of adsorption parameters such as pH, contact time, temperature, and initial concentrations on adsorption behaviors were investigated.

Özet

Bu çalışmada, çok duvarlı karbon nanotüp (MWCNT) temelli yeni hybrid material sentezlenmiştir. Sentezlenen hybrid materyal sulu ortamdan Cu(II) ve Co(II) uzaklaştımak için adsorbent olarak kullanılmıştır. Hibrid materyal üç aşamada sentezlenmiştir. Birinci aşamada Hummer metodu kullanılarak çok duvarlı karbon nanotüp okside (MWCNT-O) edilmiştir. Sonraki aşamada okside edilen karbon nanotüp 3-aminopropiltrietoksisilan ile muamele edilerek serbet -NH2 gruplarına sahip silanlanmış karbon nanotüp elde edilmiştir. Son aşamada ise silanlanmış karbon nanotüp 3,5-diklorosalisilaldehit ile tepkimesinden hybrid malzeme elde edilmiştir. Sentezlenen hybrid malzeme analtik ve spektroskopik yöntemlerle karakterize edilmiştir (FT-IR, Uv-vis, TGA, Raman, SEM, TEM, EDX ve XRD çalışmaları ile). Hibrid malzeme sulu ortamdan Cu(II) veya Co(II) iyonlarının uzaklaştı- rılmasında adsorbent olarak kullanılmıştır. Hibrid malzemenin adsorpsiyon kapasitesi üzerine pH, temas süresi, başlangıç konsantrasyon ve sıcaklık parametreleri incelenmiştir.
