| Abstract: | The technics of preparation for activated carbons from sewage sludge with H_3PO_4 by microwave radiation was researched.The effects of microwave power,radiation time and H_3PO_4 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 H_3PO_4 40%~45%.Under the conditions,the iodine value of the sludge activated carbon was 301 mg/g,BET surface area was 168 m~2/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. |
