Abstract

A method for producing modified activated carbon materials is provided comprising treating activated carbon material in a halogen containing atmosphere at a temperature of less than 180 DEG C and treating the resultant product with a nucleophilic agent at elevated temperature. Preferably the halogenation is chlorination, and preferably is carried out at 120 DEG C or less, more preferably 85 DEG C or less, and conveniently at 30 DEG C or less. The nucleophilic agent may be a liquid or a gas, and may be any agent, organic or inorganic, that has a group capable of nucleophilic displacement of the halogen, e.g. chlorine, from the carbon surface. Halogenation is carried out over several, e.g. 24 hours. The present invention relates to the production of activated carbons that have functional groups associated with their surfaces, such that species specificity in adsorption processes may be achieved.
