Quantitative Analysis of Hexavalent Chromium in Water Samples with UV-1900i


User Benefits

・UV-1900i and LabSolutionsTM UV-Vis software with CHEMetrics Chromate analysis test kit enable easy and accurate colorimetric measurement of hexavalent chromium with minimal sample and reagent preparation.


Chromium (Cr) is a group 6 transition metal that could be found naturally in rocks, plants, soil etc. There are two common forms of chromium that could occur in the environment: the trivalent form, Cr(III), and hexavalent form, Cr(VI). Cr(III) is an essential nutrient which contributes to macronutrient metabolism. However, Cr(VI), which is mainly produced by industrial processes such as electroplating and stainless-steel production, is considered a health hazard. Respiratory exposure of Cr(VI) increases the risk of lung and nasal cancer, while dermal contact may induce skin irritation and ulceration. Due to its toxicity, Cr(VI) is classified as a group 1 carcinogen by the International Agency for Research on Cancer (IARC). Therefore, it is critical to monitor its quantity in various sources such as food, water and electronics. This application news describes the use of Shimadzu’s UV-1900i and LabSolutions UV-Vis software with CHEMetrics Chromate Vacu-vials kit for the quantitation of Cr(VI) in water samples according to the American Public Health Association (APHA) Standard Method.
