SEIBOLD - Online Analyser for Aluminium

Drinking water. Important sources of elevated Al concentrations in drinking water are the use of Al-based flocculating agents such as Al2(SO4)3. Concentrations of aluminium of 0.1 mg/litre or less are achievable in large water treatment facilities.

Toxicity. There is little indication that orally ingested aluminium is acutely toxic to humans despite the widespread occurrence of the element in foods, drinking-water and many antacid preparations. It has been hypothesized that aluminium exposure is a risk factor for the development or acceleration of onset of Alzheimer disease (AD) in humans.

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.
