在半湿气氛中对吸附在活性碳纤维(ACF)上的对硝基苯酚进行了臭氧氧化反应，考察了臭氧氧化对ACF结构和化学特性的影响。对硝基苯酚的降解动力学符合准一级反应，臭氧投加量的增加对对硝基苯酚的去除有促进作用。臭氧对ACF有轻微的刻蚀作用，导致ACF的孔容减小，但原始ACF和废ACF的孔径变化也略有不同。表面含氧基团(C=O、COOH等)增加臭氧氧化后可能会对ACF的吸附性能产生影响。
Ozonation of p-nitrophenol adsorbed on activated carbon fiber (ACF) was conducted in a semiwet atmosphere, and its effect on the textural and chemical characteristics of ACF was examined. The decomposition kinetics of p-nitrophenol followed a pseudo–first-order reaction, and an increase in O3 input enhanced the removal of p-nitrophenol. Ozone slightly etched ACF and resulted in a decrease in the pore volume of ACF, but slightly different changes in pore diameter also occurred on virgin and spent ACF. An increase in the surface oxygen-containing groups (C=O, COOH, etc.) after ozonation might have influence on the adsorption capacity of ACF.
