Cadmium (Cd)

Cadmium (Cd) is found in drinking water as a result of old plumbing, industrial waste, or surface water contamination. As this is highly toxic, Cadmium levels need to be monitored and addressed.

    Cadmium Analyzer Carl Zeller Overview

    The Cadmium Analyzer Carl Zeller can perform continuous analysis of heavy metals, such as Cadmium (Cd), 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 Cadmium Analyzer guarantee 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.

    Cadmium compounds belong to the most hazardous pollutants in the environment.
    Industry. Cadmium metal is used in the steel industry and in plastics. Cadmium compounds are widely used in batteries.
    Drinking water. Contamination in drinking water may also be caused by impurities in the zinc of galvanized pipes and solders and some metal fittings. A guideline value of 0.005 mg/liter was recommended for cadmium in drinking- water.
    Toxicity. Cadmium is toxic to a wide range of organs. Primary targets are the kidneys, bone, and the lung.

    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.
