Abstract

In China,water pollution resulted from heavy metals has drawn significant attention.It is very urgent for us to adopt some effective strategies to control or treat the heavy metals in polluted water.It has been shown that using biosorption of microalgae in the treatment of heavy metals is low cost,convenient and efficient.In this paper,the status of water pollution and basic characteristics of heavy metals in water were introduced.Toxic effects of heavy metals on phytoplankton,aquatic animals,and human beings were also reviewed.Besides,three major methods commonly used in the treatment of heavy metals in polluted water were presented and compared.And then,the advantages of microalgal biosorption on heavy metals were summarized;some underlying mechanisms involved in the biosorption as well as the influence of environmental factors on the biosorption were presented and discussed.Finally,prospects and direction for the development of microalgal biosorption on heavy metals in the near further were put forward.

Key words： microalgae heavy metals water pollution biosorption
