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 – Photometric 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 evaluation is carried out photometrically with the WINLAB Data Line photometer, which enables particularly precise and reproducible measurement. The extended measuring range of 0.02 to 0.7 mg\/l is ideal for monitoring drinking water and industrial wastewater. <\/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 Objective, reproducible results without subjective color assessment<\/p>\n<\/li>\n Determination of the toxic relevant chromium form – important for health protection<\/p>\n<\/li>\n Space-saving and economical – ideal for laboratory use<\/p>\n<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":" CALDUR\u00ae Chromium Test Set – Photometric What is chromium measured for?
