Well-developed mesoporous plant-based activated carbon fibers (ACFs) with paper structure were prepared from plant pulp fibers (cotton, sisal hemp, manila hemp, softwood and bleached softwood) using phosphoric acid activation at 450℃. The structure and performance of ACFs were studied. Results show that ACFs exhibit high mesoporous rate of 72.8%-82.7%, large specific surface area of 1688-1825m²/g and average pore size of 2.53-3.31nm. ACFs show relatively high methylene blue (MB) adsorption capacity with 367.5-490.9mg/g. SHP-ACFs have the largest MB adsorption capacity, the adsorption equilibrium data follows the Langmuir model and the kinetic data could be described by the pseudo-second-order model.

用450℃的磷酸将纸浆纤维（棉，剑麻，马尼拉麻，针叶木和漂白针叶木）制成植物纤维，从而开发出具有良好纸结构的介孔植物基活性炭纤维。研究了ACF的结构和性能。结果表明，ACF具有较高的介孔率72.8％-82.7％，较大的比表面积为1688-1825m ² / g，平均孔径为2.53-3.31nm。ACF表现出相对较高的亚甲基蓝（MB）吸附容量，为367.5-490.9mg / g。SHP-ACFs具有最大的MB吸附能力，吸附平衡数据遵循Langmuir模型，动力学数据可用伪二级模型描述。
