  • China Food Industry Chitosan White Powder with 80

    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.
