Cobalt (Co)

Cobalt (Co) is a very toxic element affecting the environment. Cobalt is present in the wastewater of nuclear power plants and many other industries such as mining, metallurgical, electroplating, paints, pigments and electronic industries. Monitoring and control is therefore essential.

    Cobalt Analyzer Gustav Mahler Overview

    The Cobalt Analyzer Gustav Mahler can perform continuous analysis of metals, such as Cobalt (Co), and many other parameters in water. Technologies employed are colorimetric (photometric) and ion-selective electrodes (ISE). Direct measurements, standard addition, and titration support the ideal measurement strategy. The robust design and high-quality parts of the Cobalt Analyzer guarantees a long lifetime and minimum maintenance efforts. Low consumption of reagents and very high reagent stability ensures person-free operation. Automated calibration and cleaning steps support this goal.


    Natural sources. Natural sources of cobalt in the environment are soil, dust, seawater, volcanic eruptions, and forest fires.
    Industry. Cobalt is used for the manufacture of alloys, hard metals, and magnets.
    Drinking water. A guideline value of 0.01 mg/liter was recommended for cobalt in drinking water.
    Toxicity. As a constituent of vitamin B12, cobalt is an essential element and, so far, another physiological role of cobalt has not been demonstrated in human nutrition.


    Metal is measured as a chelate complex between metal ions in the wastewater and sensitive spectrophotometric reagent dye. Change of the intensity of the visible light throughout cuvette containing formed metal complex is directly proportional to metal concentration.
