Adsorption of Zn (II) from aqueous solution by using chitin extracted from shrimp shells

Abstract

Chitin and its derivatives (chitosan) are natural biopolymer produced from crustacean shell, which due to their active functional groups such as amine and hydroxyl have high ability to absorb heavy metals from water and wastewater. The aim of this study was to investigate zinc removal from aqueous solutions by using chitin extracted from shrimp shells.
