The capability for the adsorption of Cu (II) ion with mesoporous material SBA-15, amino-functionalized SBA-15 and mercaptopropyl-functionalized SBA-15 was investigated. XRD, FT-IR and FESEM were used for characterizing the structure and surface properties of adsorbent prepared. Effects of initial concentrations and pH on adsorption process were studied. Amino-functionalized SBA-15 was found to show the highest percentage removal of Cu (II) ion from aqueous solution compared to mercaptopropyl-functionalized SBA-15. Adsorption isothermal model was also examined. Langmuir isothermal model was found to be better fitted with adsorption process compared to Freundlich isotherm model. |
