| Abstract: | The technics of preparation for activated carbons from sewage sludge with H3 PO4 by microwave radiation was researched. The effects of microwave power, radiation time and H3PO4 solution concentration were investigated. It was showed that the technical conditions for preparation of sewage sludge-based activated carbon were microwave power 480 W, radiation time 315 s, the concentration of H3PO4 40% -45%. Under the conditions, the iodine value of the sludge activated carbon was 301 mg/g, BET surface area was 168 m2/g, the pore volume was 0.37 mL/g, and the average pore diameter was 8.8 nm. This sludge activated carbon was used to treat TNT red-water, and the effect of adsorption was satisfactory. |
