Overview of wastewater treatment methods with special focus on biopolymer chitin-chitosan

Heavy metals have substantively high values of half-lives with nonbiodegradable chemical nature. At the same time, their ionic compounds have amazing ability of ionization in aqueous media. Remediation of such metals from wastewaters has been very complex, expensive and a challenging goal for ages. Several methods have been employed to segregate heavy metals and their corresponding anions, and organic contents from wastewaters in industries. In...
