Sorbents collect specific liquids or gases depending on the composition of the material being used in the sorbent. Some of the most common sorbents used to clean oil spills are made from materials that are both oleophilic and hydrophobic, have high surface area through structural designs that include pores and capillaries, and draw in liquid through capillary action.

Fuller's earth is a term for various clays used as an absorbent, filter, or bleaching agent. Products labeled fuller's earth typically consist of palygorskite (also known as attapulgite) or bentonite. [1] Primary modern uses include as absorbents for oil, grease, and animal waste (cat litter), and as a carrier for pesticides and fertilizers.
PRP microspheres were found to be highly oleophilic as well as hydrophobic making it an ideal solution for hydrocarbon spills that contaminate water such as ocean spills, mangroves and marshes, and in groundwater aquifers. As a result, the powder was named “Petroleum Remediation Product.”
A containment boom is a temporary floating barrier used to contain an oil spill. Booms are used to reduce the possibility of polluting shorelines and other resources, and to help make recovery easier. Booms help to concentrate oil in thicker surface rather than disperse across larger areas. [1]
The workers were equipped with oil booms, vacuum pumps, oil dispersants, skimmers, absorbent materials, and other specialized oil containment and recovery equipment. Oil Spill Response Limited, which is an industry-funded organisation which assists with responses to oil spills, deployed floating containment and recovery devices to isolate oil ...
By comparison, Corexit, the oil dispersant used in the Deepwater Horizon oil spill, is rated at 54.7% effective against South Louisiana crude oil and three times as lethal to silverfish and more than twice as lethal to shrimp. [5] On May 20, US Polychemical Corporation was reported to have received an order from BP for Dispersit SPC 1000. [6]
