英文摘要：

Based on orthogonal experimental design,activated carbon with high specific surface area,abundant mesopores and favorable adsorbing effects was prepared from coconut fibers through carbonization and activation.The primary influence parameters such as the ratio of activating agent,carbonization temperature,activation temperature,activation time and heating rate on the adsorption behavior of activated carbon were investigated and the optimum preparation conditions were obtained.The activation mechanism is also discussed on the basis of experiments.
