【Abstract】 Activated Carbon Fiber was used to treat nitrobenzene simulated wastewater. Equilibrium adsorption quantity and dynamic adsorption breakthrough curve were determined by static and dynamic adsorption experiments. The results indicated that the adsorption capacity was large and adsorption rate was fast. The change of surface structure, specific surface area and pore size distribution were studied through regeneration process using high temperature. It was seen that the structure of carbon microcrystal would be etched again under high temperature conditions, so that the specific surface area was increased.更多还原
