Abstract

SBA-15 nanoporous silica was prepared and functionalized with propylamine groups via post-synthesis grafting to develop efficient adsorbents of dyes in wastewater. The materials thus prepared were then characterized by XRD, N2 ADSORPTION-desorption, and FTIR. ADSORPTION of a cationic dye, MALACHITE GREEN, on FUNCTIONALIZED SBA-15 was investigated under various conditions of pH (5, 6, and 7), temperature (10, 20, and 30oC), adsorbent dosage (0.1, 0.3, and 0.5 g/L), and dye concentration (50, 100, 150, 200, 250, 300 mg/L). Maximum equilibrium ADSORPTION capacity to achieve maximum removal percentage (R%=100%) in optimum conditions (dye concentration=100 mg/L, pH=7, adsorbent dosage= 0.3 g/L) was estimated at 333 mg/g. The Taguchi method was used to optimize the ADSORPTION performances of the materials, and then the isotherm, kinetic, and thermodynamic properties were analyzed under the optimum conditions. The results showed that the overall process was fast and its kinetics was well-fitted by pseudo-second-order kinetic model. The experimental data agreed well with Freundlich model. Therefore, the maximum amount of multilayer dye adsorbed was estimated as 500 mg/g. Based on the results obtained, this process may be regarded as an endothermic one with a negative DG, which shows the process is also spontaneous. Finally, the results indicate that the silica-based nanoporous organic–inorganic hybrid material can be a promising sorbent for the removal of MALACHITE GREEN from aquatic solutions.
