Continuous Dissolved Chrome (Cr) Analyzer | SEIBOLD

Chromium (Cr) can come from the following sources:

• Natural sources: Chromium (Cr) is widely present in the Earth’s crust, generally existing in the form of Chromium +2 or +6. Food is typically the main source of consumption.
• Industries: Chromium (Cr) is rarely found alone. As an additive, it is added as an alloy or material with the following properties: strength, hardness, permanence, hygiene, color, and resistance to temperature, wear, and corrosion.
• Drinking water: A maximum concentration of about 0.05 mg/L is recommended.

Chromium III is an essential nutrient for most animals and humans, although hexavalent chromium appears to be more toxic than trivalent chromium.

Measurement method: It is based on measuring metal ions in wastewater and their reaction to reactive dyes with spectrometric measurement. The changes in the intensity of visible light through a cuvette containing samples formed of complex metals are measured to obtain a proportional concentration of metals.
