ABSTRACT:
The present invention comprises a two-part sorbent pad having a flat, chemically treated polyethylene foam inner core completely surrounded by a flexible, durable, chemically treated polypropylene fabric cover. In use, the sorbent pad of the present invention floats on top of petroleum covered water to rapidly soak up the petroleum or oil and hold it within the inner core until it can be removed by squeezing the sorbent pad between rollers, thereby depositing the oil into a container for storage. The non-petroleum laden sorbent pad is then returned to the surface of the petroleum covered water to pick-up more petroleum. The sorbent pad is chemically treated to increase the pads ability to attract and hold oil by both adsorption and absorption and to further increase its ability to repel water.
