藻类吸附重金属的研究进展
Research advances in adsorption of heavy metals by algae
【摘要】 藻类吸附技术在处理重金属废水方面有着广阔的应用前景。介绍藻类的基本特点,藻类对有毒重金属吸附的络合、离子交换等机理,以及影响生物吸附的pH值、吸附时间、共存离子和预处理等主要因素;讨论相关的生物吸附平衡模型和动力学方程,对藻类吸附重金属研究进行了展望。
【Abstract】 Algae has a strong ability to enrich heavy metal ions.It can be used as biological adsorbent to remove and recover the heavy metals in industrial wastewater.The basic features of algae,the adsorption mechanisms and ion exchange of the toxic heavy metals are introduced.Key factors of influencing algae adsorption,such as pH value,adsorption time,coexistence ions and pretreatment are explained.Thermodynamics and dynamics of algae adsorption are also discussed.The research directions are presented.
