Description

Adsorptive Removal of Mercury from Water and Wastewater by Chitosan and its Derivatives

Fouzia Mashkoor, Abu Nasar

Mercury is one of the most poisonous heavy metals present in industrial wastewater. There is evidence showing its bioaccumulation in organism and biomagnification in food chains and having long-term toxicity. Among various adsorbents available for the confiscation of mercury from water and wastewater, chitosan has gained considerable attention. Chitosan derivatives produced by grafting, polymerization, crosslinking, N/O substitution have received significant attraction during recent years. There has been an increasing trend to produce variety of derivatized chitosan to improve the adsorption properties. This chapter briefly reviews the current researches on the applications of chitosan-based adsorbents for the elimination Hg(II). It is apparent from the literature that chitosan and its derivatives provide a better opportunity for scientists for the effective elimination of toxic Hg(II) from wastewater.
