Sauber getrennt: Die Behandlung nanometergroßer, CrVI-haltiger Mg(OH)2-Abfallpartikel mit dem Mineralisator NaHCO3+Na2CO3 überführt diesen nanoskaligen Abfall in ein nichttoxisches Volumenmaterial und eine konzentrierte Lösung des Schwermetalls. Der Prozess verläuft über zwei Stufen: Zunächst erfolgt eine Desorption von CrVI, der sich ein schnelles Wachstum von Nanokristallen bis zur vollständigen Trennung von den CrVI-Ionen anschließt (siehe Bild).
