Heavy metal pollution has raised a lot of concerns because of its bioaccumulation and non-degradability. A variety of methods have been applied in removal of heavy metals. This paper focused on the method of biosorption using biopolymer-based adsorbents in removing heavy metals from waster water. Cellulose and chitin/chitosan are abundant in supply and contain reactive functional groups. Cellulose-based adsorbents prepared from direct chemical modification or graft copolymerization are proved to show chelating ability to bind heavy metals. Chitin-and chitosan-based adsorbents have improved mechanical strength and better resistance to chemical conditions after physical or chemical modification. The regeneration and reusability of biopolymer-based adsorbents were also discussed in this paper.
