Metal cations can be adsorbed by chelation on amine groups of chitosan in near neutral
solutions. In the case of metal anions, the sorption proceeds by electrostatic attraction on …

One of the major applications of chitosan and its many derivatives is based on its ability to
bind strongly heavy and toxic metal ions. This article reviews the various classes of chitosan …

The adsorption of Cu (II) ions onto chitosan and cross-linked chitosan beads has been
investigated. Chitosan beads were cross-linked with glutaraldehyde (GLA), epichlorohydrin …

Chitin is the world's second most abundant naturally occurring polysaccharide. Much of this
is disposed of as waste from seafood crustacean, mainly in shrimps, prawns, crabs, and …

Chitosan is an optically active biopolymer that is characterized by a strong affinity for
transition metals. The polymer can be used as a support for the preparation of …

Removal of lead from aqueous solution with chitosan/PVA (poly (vinyl alcohol)) hydrogel
beads was studied in batch adsorption experiments at various solution pH values (2− 7.6) …

Chitosan based nanocomposite scaffolds have attracted wider applications in medicine, in
the area of drug delivery, tissue engineering and wound healing. Chitosan matrix …

A biosorbent was prepared by coating ceramic alumina with the natural biopolymer,
chitosan, using a dip-coating process. Removal of arsenic (III)(As (III)) and arsenic (V)(As …

Crosslinked chitosan resin chemically modified with l-lysine has been used to investigate
the adsorption of Pt (IV), Pd (II) and Au (III) from aqueous solutions. Batch adsorption studies …

Recovery of gold from electronic waste (e-waste) has received significant attention due to its
high economic value. This study reports glutaraldehyde-crosslinked chitosan (GCC) beads …
