SEIBOLD - Online Analyser for Zinc

Drinking water. Although levels of zinc in surface water and groundwater normally do not exceed 0.01 and 0.05 mg/litre, respectively, concentrations in tap water can be much higher as a result of dissolution of zinc from pipes. Drinking-water containing zinc at levels above 3mg/litre may not be acceptable to consumers.

Toxicity. Zinc or zinc compounds are not listed as suspected carcinogens. Zinc compounds can produce irritation and corrosion of the gastrointestinal tract, along with acute renal tubular necrosis and interstitial nephritis.

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.
