Abstract

Pollution caused by heavy metals is one of the most serious environmental problems today. The treatment of heavy metals is of special concern due to their recalcitrance and persistence in the environment. In recent years, various methods for heavy metal removal from wastewater have been extensively studied. This reviews the current methods that have been used to treat heavy metal wastewater and evaluates these techniques. These technologies of treatment of wastewater; precipitation, ion-exchange, adsorption, and Phytoremediation.

Biosorption of heavy metals is an effective technology for the treatment of wastewater. This chapter provides a comprehensive review of recent findings on performances, applications and biosorption by algae for sequestration of heavy metals. Biosorption kinetics and equilibrium models are reviewed. Finally, the theoretical simulation tools for biosorption equilibrium and kinetics are presented so that the readers can use them for further studies.

Keywords: Cadmium, adsorption, biomass, modeling
