| 英文摘要 | the technical feasibility of photocatalytic regeneration for coal-based activated carbon saturated with phenol was investigated in immobilized system by using tio2 and ag-tio2 as photocatalysts, and using uv lamp (lambda = 253.7 nm) as irradiation source. the factors affecting the regeneration efficiency of the activated carbon were investigated, including photocatalyst modification, regeneration temperature, oxidant additive, adsorption regeneration cycles, and ph values. based on the regeneration rate of activated carbon under different conditions, the regeneration mechanism was discussed. the effect of regeneration treatment on the pore structure of activated carbon was investigated by using n-2-adsorption isotherms. it is possible to regenerate the coal-based activated carbon through photocatalytic oxidation. the phenol adsorption capacity of activated carbon with 1.9% (ag-tio2) loading can be recovered by 78.4%, when regenerated under the conditions of ph = 13, theta = 70 degreesc and t = 72 h. the difference of phenol concentration between interior and exterior of activated carbon is the main driving force for photocatalytic regeneration. |
