甘蔗皮生物炭对苯酚的吸附特性研究
Phenol Adsorption Characteristics of Sugarcane Skin Biochar
摘要
Abstract
In order to make use of sugarcane skin resource,slow pyrolysis technology was used to prepare biochar adsorbent at 400,500 and 600 ℃ to remove phenol from wastewater.The adsorption experiments showed that the initial phenol concentration,biochar preparation temperature,temperature and time of adsorption could affect the adsorption of phenol by sugarcane biochar.The adsorption capacity of biochar prepared by three different temperatures to phenol was BC600＞BC500＞BC400.When the initial phenol concentration was 50 mg/L at 35 ℃,the removal rate of phenol was up to 96％ after 300 min.The adsorption isotherm of phenol was in line with Langmuir model and Freundlich model.关键词
