Peat Moss: A Natural Absorbent for Oil Spills

Sorption measurements show that peat moss has much stronger affinity for oil than straw, which is currently used. Microscopic studies of peat moss show a highly porous and fibrous material, and this property, associated with the phenomenon of selective absorption, had been used to absorb oil. Laboratory experiments show that peat moss absorbs up to eight times its weight of oil. Field tests have proved that peat moss can be an effective absorbent and can be used on a large scale.
