<\/a>Funktionsweise und Anwendung eines CSB-Messger\u00e4ts<\/h2>\n

Der COD ist ein h\u00e4ufig verwendeter Gesamtindex zur Bewertung des Ausma\u00dfes der Wasserverschmutzung. Zu den reduzierenden Stoffen im Wasser z\u00e4hlen verschiedene organische Stoffe, Nitrit, Sulfid, Eisensalze und so weiter, wobei organische Stoffe den gr\u00f6\u00dften Anteil ausmachen. Daher wird der chemische Sauerstoffbedarf h\u00e4ufig als Ma\u00df daf\u00fcr herangezogen, wie viel organischer Stoff im Wasser enthalten ist. Je h\u00f6her der chemische Sauerstoffbedarf ist, desto st\u00e4rker ist das Wasser mit organischen Stoffen belastet.<\/p>\n

Prinzip: Wasseprobe, Kaliumdichromat, Silbersulfatl\u00f6sung und konzentrierte Schwefels\u00e4ure werden gemischt und bei hoher Temperatur aufgeschlossen, Hochtemperaturaufschluss, Bestimmung der Absorption des dreiwertigen Chroms bei der Reduktion des Kaliumdichromats durch die Probe; der Anstieg des Absorptionswerts f\u00fcr dreiwertiges Chrom ist proportional zum CSB-Wert, und die Absorption des dreiwertigen Chroms wird in den CSB-Wert umgerechnet.<\/p>\n

Zu den wichtigsten Anwendungsbereichen z\u00e4hlen die \u00dcberwachung von Regen- und Abwasser in Unternehmen sowie die \u00dcberwachung des CSB-Gehalts im kommunalen Leitungsnetz, in Pumpwerken, im Grundwasser, in Fluss-, See- und Meerwasser.<\/p>","protected":false},"excerpt":{"rendered":"
