摘　　要：以木质素为原材料、NaOH为活化剂,通过直接炭化法制备木质素基多孔炭。以不同温度梯度进行实验,在90℃下活化36h,放入管式炉,以10℃/min的速率升至900℃,退火1.5 h制备的样品具有最佳吸附效果。在pH=9,木质素基多孔炭投加量为10 mg/L,亚甲基蓝溶液质量浓度约为90 mg/L时,最大吸附量可达235.17mg/g。Lignin based porous carbon has been prepared by direct carbonization using lignin as raw material and NaOH as the activator.After conducting experiments with different temperature gradients and a raw material ratio of 1:1,the sample is activated at 90℃ for 36 hours,then heated to 900℃ at a rate of 10℃/min in a tube furnace.After annealing for 1.5 hours,the prepared sample shows the best adsorption effect.When the pH value is 9,the dosage of lignin based porous carbon is 10 mg/L,and the mass concentration of methylene blue is about 90 mg/L,the maximum adsorption capacity can reach 235.17 mg/g.
