摘要：Silver, carbon-doped TiO 2 absorbent was obtained using hydrothermal method with titanium sulfate as a titanium source. Reactive brilliant red X-3B was used as a target degradation material to evaluate its adsorption activity. Physicochemical properties of the absorbent was characterized by analytical techniques such as XRD, SEM-EDS, TG-DTG, TEM-HRTEM, BET, and XPS. The results showed that the synthesized samples has a phase of anatase with typical mesoporous structure, and it also has a good adsorption activity of reactive brilliant red X-3B. The Ag-C-TiO 2 (calcined at 500°C) absorbent's discoloration rate for reactive brilliant red X-3B (50 ppm) reached 97% after adsorption for 60minutes at absorbent of 1.5 g/L(50 ppm reactive brilliant red X-3B solution), and solution pH of 7~9. This type of Ag-C co-doped TiO 2 could potentially be used as absorbent for dye wastewater treatment based on its unique physicochemical properties
