Abstract :In this study, a new multi-walled carbon nanotubeinsert ignore into journalissuearticles values(MWCNT); based hybrid material was obtained and used as adsorbent for the removal of Cuinsert ignore into journalissuearticles values(II); and Coinsert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(FT-IR, UV-Vis., TGA, Raman Spectra, SEM, TEM, EDX and XRD studies);. The hybrid material was used as adsorbent for the removal of Cuinsert ignore into journalissuearticles values(II); and Coinsert ignore into journalissuearticles values(II); ions from aqueous solutions. The effects of adsorption parameters such as pH, contact time, temperature, and initial concentrations on adsorption behaviors were investigated.
