EXPO 2008: Diamantelektroden reinigen Wasser

(PresseBox) (München, )
Wasser reinigen und desinfizieren ohne Chemie - diamantbeschichtete Elektroden machen es möglich. Wie das geht, wird auf der EXPO 2008 (14. Juni - 14. September) in der nordspanischen Stadt Zaragoza vorgestellt.

Glitzernde Diamanten sind bislang vor allem als wertvoller Schmuck bekannt. Doch die Edelsteine helfen auch, Abwasser zu reinigen und Wasser zu desinfizieren. Der Trick: An mit leitfähigem Diamant beschichteten Elektroden bilden sich im Wasser Hydroxylradikale. Dieses hochwirksame Oxidationsmittel vernichtet alle kohlenstoffhaltigen Substanzen - also die organische Schmutzfracht von Lösungsmitteln bis zu Bakterien und Pestiziden. Zurück bleiben nur harmlose Salze und Kohlendioxid, das als Gas entweicht.
