ABSTRACT:
The sorbent of the present invention is useful in adsorbing petroleum-based products such as oil and gasoline, particularly from the surface of water. This sorbent, which is comprised of about 5 wt. % to about 70 wt. % cured, cross-linked resin and about 30 wt. % to about 95 wt. % fibers, selectively adsorbs the petroleum-based product due to its hydrophobicity.
