中文摘要: 以甘蔗渣为原料,在不同操作条件下制备得到活性炭,测定了相应的活性炭对亚甲基蓝脱色的吸附值,并研究了亚甲基蓝吸附值与活化剂浓度、活化时间和活化温度之间的关系.实验结果表明,浸渍剂浓度是用磷酸活化法制备活性炭的最重要的影响因素在磷酸浓度为40 wt%,活化时间为12 h,活化温度为500℃时,甘蔗渣活性炭的吸附能力最高,亚甲基蓝的吸附量达到294.866 mg/g.
Abstract:Activated carbon is prepared from the raw materials of bagasse under different operating conditions.The methylene blue adsorption value of different activated carbon is also tested.The relation between methylene blue adsorption value and impregnant,carbonization time and activation temperature is studied and discussed.As can be seen from the results,the impregnant concentration has the most important impact on methylene blue adsorption value.The bagasse activated has its highest methylene blue adsorption value of 294.866 mg/g under the following conditions:phosphoric acid concentration is 40 wt%,and activation time is 12 h,activation temperature is 500 ℃.
