| 摘 要： | 以木质纤维素为吸附剂,分析吸附时间、初始浓度、pH值、温度等因素对木质纤维素吸附亚甲基蓝阳离子染料的影响.结果表明:木质纤维素对亚甲基蓝吸附300min后达到平衡,初始浓度超过180mg/L后吸附量不再增加,pH值由2增加到8时,吸附量由23.0mg/g增加到40.1 mg/g,温度对吸附量呈现先增大后减小的趋势.讨论...

| Abstract: | Using lignocellulose as an adsorbent,the effects of parameters such as adsorption time,initial concentration,pH value and temperature on the removal of methylene blue dye ion from aqueous solutions were investigated.The results showed that adsorption equilibrium of lignocellulose for methylene blue reached after 300 minutes.The adsorption capacity of lignocellulose reached steady state when the initial concentration exceeded 180 mg/L.The adsorption capacity increased from 23 mg/g to 40.1 mg/g when the solut... |
