【 摘 要 】

In this paper, the adsorption behavior of nitrobenzene from wastewater on modified activated carbon fiber was studied. The results showed that HNO3 modified activated carbon fiber had the best adsorption performance. The optimum adsorption conditions were absorbent dosage 0.8g/50mL, the equilibrium time 60 minutes, and the removal of nitrobenzene increased with increasing the temperature of the system. The kinetics of adsorption indicated that the adsorption followed second-order kinetic equation.
