A METHOD OF MARKING MESOPOROUS ACTIVATED CARBON ON CELLULOSIC FIBROUS MATERIALS FOR USE IN A WOULD DRESSING

摘要

A wound dressing having high adsorbency for bacterial toxins and the like comprises a layer of activated carbon wherein at least 10% of the pore volume of the activated carbon is represented by mesopores. The mesoporous activated carbon may be made by impregnating a cellulosic fibrous material with a liquid medium containing phosphate and an alkali metal, then carbonising and activating the impregnated fibrous material by heating in a suitable atmosphere.
