Beschreibung
Zusammenfassung:	Foams, which is a composite foam of polyurethane foam, polyethylene foam, and/or polystyrene foam, comprising an iron oxyhydroxy granules as an adsorbent composition (5-45 wt.%, based on the total mass of foam), comprises cavities filled with the iron oxyhydroxy granules having a Brunauer-Emmett-Teller (BET) surface area of greater than 100 m 2>/g, and a mean particle size of 0.5-2 mm. An independent claim is included for a use of the foams comprising an adsorbent composition as above, for removing pollutants and/or heavy metals, which is finely processed and used in filter casings of pumps for aquaria, garden ponds and/or waste water purification plants.
