Abstract Chitoson, a high molecular weight polymer, has the ability to sorb metals and form chitosan‐metal complexes. A complex using copper has been prepared and its desorption characteristics have been studied. The slow release of copper is of potential use in anti‐fouling paints and therefore the desorption of copper has been studied under various environmental conditions. Desorption rates were high in distilled water but low in sea water, and after further comparative tests with commercial marine paints, it was concluded that copper‐chitosan complexes are not as effective as the cuprous oxide anti‐fouling agent currently used in marine paint formulations.
