| Abstract: | A new catalytic spectrophotometric method for determining trace amounts of manganese has been developed. The method is based on catalytic oxidation of morin by hydrogen peroxide. Manganese has catalytic effect. The detection limit for manganese is 0.004 microg/mL. The linear range of the determination is 5-80 ng/mL of manganese. The method has been used to determine trace manganese in wine. |
