SEIBOLD - Online Analyser for Cobalt
Sources: Natural sources. Natural sources of cobalt in the environment are soil, dust, seawater, volcanic eruptions and forest fires. Industry. Cobalt is used for for the manufacture of alloys, hard metals and magnets. Drinking water. A guideline value of 0.01 mg/litre 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 chelate complex between metal ions in the waste water 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.
