A filter material by which substances contained in gaseous or liquid media can be removed comprises a product in the form of a matrix of activated carbon. The product has uniformly dispersed therein at least one metal taken from the group Ca, Mg, Ba, Al, Cu, and the transition metals and is obtained by chemically reacting cations which comprise at least one of said metals from said group with anionic groups chemically bound to a polyhexose derivative. |
