| 摘 要： | 以聚丙烯塑料和梧桐锯末为原材料,无水K2CO3为活化剂,采用干混合法制备高介孔率柱状活性炭.通过单因素实验,探究了塑料含量、盐料比、活化温度及活化时间对活性炭吸附亚甲基蓝(MB)性能的影响.结果表明:当塑料含量为20%、盐料比为2.5、活化温度为950℃、活化时间为80 min时,所制备的活性炭具有较高的MB吸附量(322.9 mg·g-1).所制备的活性炭具有发达的微观孔隙结构,其比表面积达到1461.99m2·g-1,平均孔径为3.23 nm,总孔容为1.04 cm3·g-1,其中,介孔孔容为0.80 cm3·g-1,介孔率超过70%,充分说明该方法可制备优质高介孔率柱状活性炭.
