Chromat (Cr(Vl)) ist eine oxidierte Form des chemischen Elements Chrom (Cr)), die in vielen natürlichen und synthetischen Materialien vorkommt. Chromat ist ein starkes Oxidationsmittel und kann in hohen Konzentrationen toxisch und krebserregend sein, wenn es von Menschen und Tieren eingeatmet oder konsumiert wird.
In der Wasserbehandlung und -analyse ist Chromat von Bedeutung, da es in einigen Regionen aufgrund von natürlichen Vorkommen oder menschlichen Aktivitäten wie Bergbau und Industrie in erhöhten Konzentrationen im Wasser vorkommen kann. Chromat kann aufgrund seiner toxischen Wirkung eine Bedrohung für die Umwelt und die Gesundheit von Tieren und Menschen darstellen.
In vielen Ländern werden Grenzwerte für Chromat im Trinkwasser festgelegt und überwacht, um sicherzustellen, dass das Wasser sicher und gesund ist. Chromat wird typischerweise mittels der Ionenchromatographie oder der Farbmetrie gemessen.
In der Wasserbehandlung kann Chromat durch verschiedene Methoden wie Adsorption, Fällung oder Membrantechnologie entfernt werden. Dies ist ein wichtiger Schritt in vielen Wasserbehandlungsprozessen, um sicherzustellen, dass das behandelte Wasser den geltenden Standards und Richtlinien entspricht und sicher für den menschlichen Verzehr ist.

Testoval Chromate Reagents Refill Pack The refill pack allows additional analyses to be carried out without the need for a completely new test kit. Testoval Chromate reagents enable fast manual analysis of chromate content in water in the concentration range of 0–5 mg/l Cr. The Testoval Chromate reagents refill pack is used to replenish existing Testoval Chromate test kits for manual water analysis. With the included reagents, the chromate content in water samples can be determined reliably. During the analysis, the water sample reacts with the reagents and produces a distinct color change, which is then compared with the corresponding scale using the Testoval color comparator. This allows the chromate concentration to be read easily within 3 minutes. Why buy the Testoval Chromate refill pack from Heyl? compact reagent bottles for storage and transport fast and reliable color development practical refill solution for Testoval Chromate test kits Possible application areas monitoring of industrial and wastewater treatment plants laboratory examination of water samples environmental analysis and water monitoring Technical data 1 set of reagents (1xA, 2xB) Number of analyses: approx. 180 Measurement time: approx. 3 minutes The individual values 0.1 mg/l, 0.25 mg/l, 0.5 mg/l, 1 mg/l, 2.5 mg/l and 5 mg/l can be read by optical color comparison. The scope of delivery includes only the set of reagents. The color comparator or the complete colorimetric test kit are also available in our shop. Also available in our shop: Item number 410532: Complete Set Testoval Chromate Test Kit Item number 410534 Replacement Color Comparator
Testoval Chromate Test Kit – manual analysis of chromate content Complete Testoval Chromate color comparison test kit for fast manual analysis of chromate content in water in the concentration range of 0–5 mg/l Cr. The reagents included in the set are sufficient for approximately 180 analyses. The Testoval Chromate test kit from Heyl is a color comparison analysis device for the determination of chromate (CrO₄²⁻) in water. The measurement is carried out by a chemical reaction with the included reagents, which produce a color change. The sample is then compared with a scale in the color comparator, allowing the chromate value to be read easily and reliably. Advantages of the Chromate Color Comparison Test Kit from Heyl reliable results for routine checks easy handling for laboratory and field use fast determination through optical color comparison complete set with reagents and color comparator Possible Application Areas drinking and process water analysis monitoring of wastewater and environmental samples service and maintenance work on water systems laboratory and industrial testing Technical Data Number of analyses: approx. 180 Measurement time: approx. 3 minute The individual values 0.1 mg/l, 0.25 mg/l, 0.5 mg/l, 1 mg/l, 2.5 mg/l and 5 mg/l can be read by optical color comparison. The scope of delivery includes three reagents as well as a color comparator for simple concentration determination.
