چکیده:

In this study, Mesoporous SBA-15 was synthesized under acidic condition at 40 C with a non-ionic triblock copolymer (P123) as the template. The synthesis gel composition used was 1 SiO2:0.017 P123:2.9 HCl: 202.6 H2O. Functionalization of SBA-15 with Fe (NO3)3.9H2O by post-synthesis method was performed under reflux for 1.5 h. The structural order and textural properties of the prepared materials were studied by XRD, FTIR, and nitrogen adsorption. Fe-doped mesoporous silica SBA-15 has been studied as an absorbent for carbazole adsorbent from water-ethanol solutions at room temperature. Comparing with pure SBA-15, Fe-doped SBA-15 shows improved adsorption properties.
