PITTSBURGH, June 7 (UPI) — A U.S. engineering professor says he has developed a polymer-based filter that successfully cleaned water while recovering oil in Gulf of Mexico tests.
University of Pittsburgh Assistant Professor Di Gao said he developed the technique in response to the massive oil leak that developed from the April 20 explosion of a BP oil rig in the gulf. He said the technique combines an ordinary cotton filter coated in a chemical polymer that blocks oil while allowing water to pass through. Gao said the result is the filter simultaneously cleans water and preserves the oil.
Gao has submitted his idea through the Deepwater Horizon Response Web site managed by the consortium of companies and government agencies overseeing the disaster response.
In a 2009 article in the journal Langmuir, Gao reported the creation of a nanoparticle-based solution that can prevent the formation of ice on solid surfaces, from power lines to airport runways and roads.
