Gold Removal and Recovery using Mesoporous Silica Adsorbents
Two gold-selective adsorbents were prepared from MCM-41 by grafting amino and thiol groups. The mesoporous silica adsorbents possess higher adsorption capacity for gold compared to activated carbons. The OMSNH2 adsorbent was able to selectively remove and adsorb gold from solutions containing copper. Pure gold was recovered by a simple acid wash and the regenerated adsorbents could be reused. T...
متن کاملCarboxyl-functionalized mesoporous silica-carbon composites as highly efficient adsorbents in liquid phase
Mesoporous silica-carbon composites functionalized with acidic oxygen groups were prepared by oxidation of a layer of carbon deposited inside the silica pores. The synthesis procedure involved the following steps: a) removal of the silica surfactant, b) impregnation of the silica pores with a carbon precursor, c) carbonization and d) oxidation with ammonium persulfate. The resulting silica-carb...
متن کاملUnusual ceria dispersion formed in confined space: a stable and reusable adsorbent for aromatic sulfur capture.
An unusual ceria dispersion was achieved by using the confined space between template and silica walls in as-prepared mesoporous silica, for the first time. The new adsorbents exhibit high adsorptive desulfurization activity and, more importantly, excellent stability and reusability, which is impossible to realize with conventional adsorbents.
متن کاملSilica-based mesoporous organic-inorganic hybrid materials.
Mesoporous organic-inorganic hybrid materials, a new class of materials characterized by large specific surface areas and pore sizes between 2 and 15 nm, have been obtained through the coupling of inorganic and organic components by template synthesis. The incorporation of functionalities can be achieved in three ways: by subsequent attachment of organic components onto a pure silica matrix (gr...
متن کاملDissolution of Mesoporous Silica Supports in Aqueous Solutions: Implications for Mesoporous Silica-based Water Treatment Processes.
Under pH 7 - 10 conditions, the mesoporous silica supports proposed for use in water treatment are relatively unstable. In batch experiments conducted in pH 7 solutions, the commonly used support SBA-15 dissolved quickly, releasing approximately 30 mg/L of dissolved silica after 2 hours. In column experiments, more than 45% of an initial mass of 0.25 g SBA-15 dissolved within 2 days when a pH 8...
