摘要
藻类对重金属有很好的吸附作用 ,并具有成本低、选择性好、吸附量大、浓度适用范围广等众多优点 ,而且带来的环境污染小 ,可作为一种廉价吸附剂。但目前存在机械强度低 ,可操作条件差等缺点 ,限制了在实际中的应用。本文在综述和分析藻类吸附重金属研究机理基础上 ,着重介绍了吸附剂的改性处理方式及吸附特点和效果的分析 。
In recent years, there is an increasing research interest in biosorption of heavy metals by nonliving algae, which has many advantages, such as lower cost, good selectivity, small concentration limitation and so on, compared with the traditional methods. The main condition of research on biosorption of heavy metals by nonliving algae is reviewed in this paper, including the effect of pretreatment and biosorption mechanism.
