The sorption properties of chitosan-carbon fibrous materials

The kinetics and equilibrium of sorption of copper(II) ions on natural biopolymer chitosan, activated carbon fiber, and composite materials prepared by electrochemical modification of activated carbon fibers with chitosan were studied. The influence of the conditions of modification of the microporous carbon matrix on the sorption properties of composite materials with respect to copper(II) was investigated. It was shown that changes in modification conditions could be used to control the sorption properties of chitosan-carbon materials. The mechanisms of copper(II) ion absorption by the sorption materials studied were considered.
