摘　　要：采用活性炭纤维处理硝基苯废水 ,通过静态与动态吸附实验 ,测定了表观平衡吸附量、动态穿透曲线 .研究表明该材料处理硝基苯废水吸附容量大 ,吸附速度快 .研究了高温再生后活性炭纤维的表面纤维结构、比表面积和孔径分布的变化 。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.
