Abstract
This paper presents the results for contribution of determining the manganese from waters and steel. Manganese, due to its properties, cannot be found but in acid waters and usually associated with iron. In small amounts, the manganese is a necessary nutrient above all as activator of certain enzymes. In large amounts, though, coming from contaminated waters, the manganese is noxious and may cause brain damage l. It is considered that drinking water should not contain more than 0,1 ppm manganese. From the studies carried out , the tiobis-β-naftolul dissolved in etilic alcohol or isobutilic alcohol may be used to determine the Mn (II) ion , under certain conditions as described in the paper. To determine manganese (II) in water, a photometric extraction method has been developed. The method is new, useful and accurate and enables determining Mn in surface, underground and fishery waters.
