摘  要:
重金属离子在环境中十分稳定,很难降解,通过饮水和食物链对人类产生严重的危害。如何减少工业和城市生活废水中的重金属对环境的污染已经成为我国环境保护的重大课题之一。大量研究表明,利用植物材料可以有效地去除废水中的重金属。本文概述了用于重金属吸附的主要植物材料种类及其物质组成和预处理方法,总结了影响植物材料吸附重金属元素的五个主要因素,吸附机理的研究近况,并对植物材料吸附重金属的前景进行了展望。

摘  要:
Heavy metal ions are very stable and hard to be removed from the natural environment,which are greatly harmful for human health by drinking water or food chain.How to reduce these heavy metallic pollutants from industrial production and city daily life is getting one of the most emmergent enviromental protection issues in our country.A large amount of researches show that some plant materials can eliminate heavy metals from waste water effectively.In this paper,the types,constituents and pre-treatment methods of the main plant materials used to absorb heavy metals are described,five factors affecting the absorbtion process are summarized and the prospect of such biosorption on heavy metals are pointed out.
