- Abstract
Activated carbon was prepared from Salix psammophila, and titanium dioxide was loaded on granular Salix psammophila activated carbon by sol-gel method. The effects of activated carbon particle size, phosphoric acid concentration, activation temperature and activation time on the regeneration performance of titanium dioxide loaded on Salix psammophila activated carbon were mainly investigated. The results show that the regeneration performance increases with the decrease of activated carbon particle size, and increases with the increase of phosphoric acid concentration, activation temperature and activation time. The optimal process is 0.7 mm particle size,20% phosphoric acid concentration,700 °C activation temperature and 1.5 h activation time. Structure study shows that titanium dioxide is coated on the surface of activated carbon in the form of anatase film, and titanium dioxide loaded on Salix psammophila activated carbon has abundant pores, with specific surface area of 1 277 m2/g and pore volume of 0. 567 cm3/g.
