Abstract

Ganz wenig genügt: Der Gehalt von Arsen in Brunnenwasser in Bangladesh sowie in käuflichem Trinkwasser und in Leitungswasser im US-Staat Mississippi kann mithilfe eines Assays auf der Basis dynamischer Lichtstreuung (DLS) angezeigt werden. Die hochempfindliche und selektive colorimetrische Analyse (siehe Bild) weist Arsen in Konzentrationen von nur 3 ppt nach.
