Abstract

In order to develop biomaterials useful in reconstructive surgery, mechanism of adsorption of chitosan onto activated carbon has been investigated. Activated carbons have been characterised using SEM, NH₃ adsorption and ¹²⁹Xe NMR spectroscopy. Adsorption of chitosan on activated carbon in acid aqueous solution increases when the degree of acetylation of chitosan decreases. Sterilization does not modify the adsorption capacity of the studied sample of activated carbon.
