fuel oil, diesel, gasoline, and especially crude oil arrive after accidents frequently in waters. It is possible only with great effort to collect again. In the future, it is child’s play. Then, the hydrocarbons are easily removed via magnetic. “So a nonsense”, will say many, and they seem to be right. Hydrocarbons are finally not magnetic.
magnetic iron oxide binds hydrocarbon itself
with a trick they will yet. A team led by Marcus Halik, Professor of materials science at the, iron oxide particles have Friedrich-Alexander University of Erlangen Nuremberg, so prepared that they bind hydrocarbon itself. These are magnetic, so the collection works. It then separates the particles of the hydrocarbons both factions can be used.
particle volume as skimming the impurities – stay behind dispersions, i.e. mixtures of water and hydrocarbons – succeeds with iron oxide particles prepared in a wholly owned Distance. They are also extremely effective. You collect as many molecules that their volume at the end is 14 times greater than the particle core. Thus, the process is extremely efficient and thus inexpensive. So far, only parts of impurities can be collect. Bacteria that occur in waters by nature will do the rest. But they work slowly. Often take years before a contaminated water is completely clean. During this time, plants and animals suffer the pollution.

the industry is already interested in the system for contamination with different hydrocarbons
tested researchers. Also they changed the temperature and experimented around the lakes and sea water with different waters. By computer simulation, they modified the function layer that attractive on hydrocarbons, so that they have increased the effectiveness. The presented system could help in the future to defuse triggered environmental disasters by oil spills. Currently the FAU scientists working together with partners in the industry to develop a production technology for the mass of particles and to transfer the concept to real-world applications for water cleaning.
