Abstract

An improved method of producing activated carbon fabrics from cotton fabrics involves washing a piece of cotton fabric with a detergent before soaking the washed piece of cotton fabric in an acidic chemical such as phosphoric acid for a specific amount of time, and then drying the soaked piece of cotton fabric in an oven. After the fabric has been dried, it is heated in a furnace which is fed with a flow of nitrogen gas as the temperature of the furnace is gradually increased to a pre-determined temperature and kept at the pre-determined temperature for an extended amount of time, before allowing the temperature to gradually return back to room temperature. After being removed from the furnace and being washed with distilled water to remove any remnants of phosphoric acid, the resulting product is an activated carbon fabric.
