Chitosan templated synthesis of mesoporous silica and its application in the removal of Cd(II) and Pb(II) from water |
| 초록 |
Mesoporous silica (MS) precursor to 3-Aminopropyltriethoxysilane (APTES) was synthesized using chitosan as a template. The synthesized MS was characterized by SEM, XRD, FT-IR and BET surface area analyzer. The specific surface area of MS was measured to be 511.77 m2/g and the pore size and pore volume were found to be 3.38 nm and 0.036 cm3/g, respectively. The synthesized MS was utilized for the adsorption of Cd(II) and Pb(II) from aqueous solutions. The solution pH significantly affects the uptake of these two metal ions and high removal percentage was observed at higher pH. The equilibrium state sorption data follows Langmuir adsorption isotherm. Adsorption process was fast and the kinetic modelling suggested that the adsorption of Cd(II)/Pb(II) by MS occurred through second order reaction. Furthermore, fixed bed column adsorption was conducted and the loading capacity for Cd(II) and Pb(II) were found to be 11.54 and 8.59 mg/g, respectively |
