Active carbon adsorbents were prepared from natural elutrilithe by chemical activation with K2CO3. The effect of pyrolysis temperature and time and K2CO3/elutrilithe ratio on the surface area, porosity, and ash content of the adsorbents was studied. Various prior and post treatments have been tried to improve the quality of the adsorbents. An ideal active carbon adsorbent with a BET surface area of 1236 m2/g and a total pore volume of 0.679 cm3/g has been obtained. The adsorbent is hydrophobic in nature and exhibits large adsorption capacities for various phenolic compounds from aqueous solutions. Copyright 1997Academic Press
活性碳吸附剂由天然漂积黏土经碳酸钾化学活化制备而成。研究了热解温度、时间以及碳酸钾与漂积黏土的比例对吸附剂表面积、孔隙率和灰分含量的影响。尝试了各种预处理和后处理方法以提高吸附剂的质量。已获得一种理想的活性碳吸附剂,其BET表面积为1236平方米/克,总孔体积为0.679立方厘米/克。该吸附剂本质上是疏水的,对水溶液中的各种酚类化合物具有较大的吸附容量。版权所有1997学术出版社
