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 ,并探讨了进一步改性处理方式和应用前景 Algae has a good adsorption of heavy metals, and has the advantages of low cost, good selectivity, large adsorption capacity, wide range of application of a wide range of concentrations, and the resulting environmental pollution is small, can be used as a cheap adsorbent. However, there are shortcomings such as low mechanical strength and poor operating conditions, limiting the practical application. On the basis of reviewing and analyzing the research mechanism of algae adsorption on heavy metals, this paper mainly introduced the modification of adsorbents and the analysis of their adsorption characteristics and effects, and discussed the ways of further modification and application
