Water Soluble Chitosan Derivatives 

The Chitosan for coagulation and recovery of suspended solids in food processing wastes, with reduction of suspended solids of 65%-99% has been investigated. It have been applied as a chelating polymer for binding harmful metal ions, such as copper, lead, mercury, and uranium, from Wastewater. chitosan has been employed as an excellent adsorbent for sorption of dyes and polychlorined biphenyls (PCBs) from waste water. Adsorption is the ability of certain solids to selectively concentrate solute from solution onto their surface. Chitosan has demonstrated the potential to adsorb significant amounts of metal ions, and this has generated a large amount of interest in assessing its feasibility to remove metal ions over a wide range of effluent systems and types.
