Abstract
Iron is the second most abundant metal in the earth's crust, Elemental iron is rarely found in nature, as the iron ions Fe2+ and Fe3+ readily combine with oxygen- and sulfur-containing compounds to form oxides, hydroxides, carbonates, and sulfides, so it is more commonly exists in the form of its oxides. So in order to provide safe drinking water to the public, both government and private organizations should measure iron content in water both drinking and other tap waters in every sector like schools, hospitals, industries etc.According to WHO and U.S. Federal regulations limit the amount of iron to less than 0.3 ppm (0.3 mg/L) in municipal drinking water. Although iron is only toxic at very high concentrations, it acts as a useful surrogate for other heavy metals. So our research mainly focuses on measuring iron content in tap water and determines whether or not the water meets the standards. Solutions containing iron are colorless at low concentration so the iron solutions are colored by adding a complexing agent and analyzed using a spectrophotometer.
