REMOVAL OF HEAVY METAL IONS THROUGH BIOSORPTION BY ACTIVATED SLUDGEAHMAD ASHFAQAbstract The presence of heavy metals in the environment can be detrimental to a variety of living species, including human beings. A variety of biological materials have received increasing attention for heavy metal removal and recovery due to their good performance, low cost and large available quantities. Biosorbents are cheaper, more effective alternatives for the removal of metallic elements, especially heavy metals from aqueous solution. In this paper, based on the literature, the emphasis is laid on biosorption performance, modification, regeneration/reuse, modeling of biosorption and potential application. The sorption isotherms were described by using the Langmuir and Freundlich models and the kinetic experimental data were correlated by the pseudo first and second-order kinetic models.
