Continuous Cobalt (Co) Analyzer | SEIBOLD

Cobalt is found in natural sources such as soil, dust, seawater, volcanic eruptions, and forest fires, and is used in industries for making alloys, hard metals, and magnets. In drinking water, the recommended maximum concentration is 0.01 mg/L. It is essential for human health as part of vitamin B12.


Cobalt (Co) can come from the following sources:

  • Natural sources: In the environment, sources include soil, dust, seawater, volcanic eruptions, and forest fires.
  • Industries: Cobalt is used in the manufacture of alloys, hard metals, and magnets.
  • Drinking water: A maximum concentration of 0.01 mg/L is recommended.

As a component of vitamin B12, cobalt is an essential element, and so far, no other physiological role of cobalt in human nutrition has been proven.

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