利用喜旱莲子草制备活性炭,选择了活化剂、活化剂浓度、碳化时间、碳化温度等作为实验的四个因素,每个因素选取三个水平,采用正交实验法,得出了最佳制备条件:以2mol/L的H3PO4作为活化剂,碳化温度400℃,碳化时间1h。比较了不同时间、不同活性炭用量、不同温度下,喜旱莲子草基活性炭对苯酚的吸附效果。此外,动态吸附实验表明:提高活性炭用量(即增加填料高度),降低进水苯酚浓度以及减小进水流量均能相应延长喜旱莲子草基活性炭去除苯酚到达穿透点的时间,从而增加最大吸附容量。

For preparation of alligator weed based activated carbon, the activator, activator concentration, carbonization time and carbonization temperature were selected as the four factors Of orthogonal experiment, and three levels were selected for each factor. The best preparation conditions drawn from the orthogonal experiment were as follows: with 2 mol/L H2O4 as activator, carbonized at 400 ℃ for 1 h. The adsorPtion of phenol by alligator weed based activated carbon under the conditions of different time, different activated carbon dosage and different temperatures also were studied. In addition, the dynamic adsorption experiments showed that the time for reaching the penetration point could be extended accordingly by increasing the amount of activated carbon (ie increasing packing height), reducing the influent phenol concentration as well as reducing the iniluent flow, and thereby the maximum adsorption capacity was increased.
