Chromium is a heavy metal that occurs in various oxidation states. Hexavalent chromium (chromium VI or chromate), which is considered toxic and carcinogenic, is particularly relevant for water analysis. Chromium mainly enters the water through industrial processes such as electroplating, tanning, metal finishing and steel production. Natural sources such as chromium-containing rocks can also contribute to contamination. <\/p>\n
The limit value for drinking water is 0.05 mg\/l chromium<\/strong> (Drinking Water Ordinance). As chromium VI is considerably more toxic than chromium III, particular importance is attached to the determination of this form in water monitoring. Regular monitoring is essential for the protection of health and compliance with environmental regulations. <\/p>\n The CALDUR\u00ae Chromium Test Set – Colorimetric works according to the proven diphenylcarbazide method. Hexavalent chromium (Cr VI) reacts with 1,5-diphenylcarbazide in an acidic solution to form a violet-red color complex. The intensity of the coloration is directly proportional to the chromium concentration in the sample. <\/p>\n The measured value is determined by direct color comparison with a supplied 6-stage color chart. This colorimetric method enables fast and reliable on-site determination without the need for expensive laboratory equipment. Optionally, the sample can also be evaluated photometrically with the WINLAB Data Line photometer. <\/p>\n Ideal for on-site use – saves time and enables immediate decisions<\/p>\n<\/li>\n Perfect for compliance with the Drinking Water Ordinance and for sensitive applications<\/p>\n<\/li>\n Cost-efficient for regular inspections in industry and waterworks<\/p>\n<\/li>\n Flexible for simple on-site tests or precise laboratory analyses with photometer<\/p>\n<\/li>\n Determination of the toxic relevant chromium form – important for health protection<\/p>\n<\/li>\n Safe transportation and protection of reagents – durable and reliable<\/p>\n<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":" CALDUR\u00ae Chromium test set – Colorimetric What is chromium measured for?
