Allgemeine Beschreibung
Der MQuant® Chromat-Test umfasst Teststreifen und alle erforderlichen zusätzlichen Reagenzien. Er kann zur Überwachung des Abwassers aus Galvanik- und Beizanlagen sowie von Zement und für die schnelle und zuverlässige Bestimmung von Chrom(VI)-Salzen verwendet werden. In einer schwach phosphorhaltigen Lösung reagieren Chrom(VI)-Ionen mit Diphenylcarbazid, um Chrom(III) und Diphenylcarbazon zu erzeugen, die einen rotvioletten Komplex bilden. Die Chromatkonzentration wird durch Sichtvergleich der Reaktionszone des Teststreifens mit den Feldern einer Farbskala semiquantitativ gemessen. Die Teststreifen sind ideal für die wirtschaftliche und schnelle Vorprüfung einer Probe, um die Chromatkonzentration und einen möglichen Verdünnungsfaktor zu bestimmen, bevor eine quantitative Methode wie ein Spectroquant® angewandt wird.
