采用磷酸二氢钾活化原材料柚子皮,分别在300℃和600℃对活化后柚子皮进行炭化,制得吸附剂(CC300和 CC600),通过静态吸附实验研究了炭化柚子皮对双酚A的吸附性能。采用比表面积分析仪对炭化柚子皮进行表征,实验考察了pH值、吸附时间和温度对双酚A吸附的影响,并详细研究了炭化柚子皮对双酚A的吸附行为和机理。结果表明,高温炭化柚子皮(CC600)吸附双酚A能力比低温炭化(CC300)的强,其吸附较好地满足Langmuir和Freundlich等温方程;动力学研究表明,其吸附速率快,在150 min内能达到吸附平衡,准二级动力学模型较好地描述该吸附行为,相关系数高达0.99;计算了热力学参数?G、?H和?S的值,?G为负值,说明该吸附...

Activated carbon prepared from pomelo peel using monopotassium phosphate as an activator at 300°C and 600°C was utilized as adsorbent(CC300 and CC600) to remove bisphenol-A from aqueous solution. The carbonized pomelo peel was characterized by Brunauer-Emmett-Teller (BET) analysis. Batch experiments were conducted to study the effects of pH, adsorption time, and temperature on bisphenol-A adsorption. The results showed that the CC600 sample had greater adsorption efficiency than the CC300. The Langmuir and Freundlich models were applied to de...
