Abstract:
Heavy metal pollutionin result of human activities such as mininghas ecome a criticalenvironmental issue nowadays. Various methods for removing heavy metal from industrial wastewater have been investigated. This paper reviews an economic and environment friendly process known as biosorptionBiosorption is a potential alternative to the conventional treatment processes such as adsorption on activated carbon.Some factors such as solution pH may affect biosorption process.The equilibrium of biosorption process can be described by isotherm models such as Langmuir and Freundlich.Chitosan, zeolites and clay are the sorbentswhich reviewed in this paper andcompared tocommercialactivated carbonin aspect of efficiency and price.
