Study on the Determination of Trace Manganese by Luminol-Mn(Ⅱ)-KIO4 Ghemiluminescence System

Abstract

Abstract: Asensitive and selective analytical method has been developed for determination of trace amount of manganese, it bases on luminol-Mn( E )-KIO₄ chemiluminescence system and triethanolamine as activator. The detection limit of the method is 8×10^-6μg/mL of Mn( Ⅱ). The linear range of the working curves is 10^-5~0.1μg/mL. The relative standard deviation is less than ±3%. The method was applied to determination of manganese (Ⅱ) in well water and human hiar with satisfactory results.

Key words: Chemiluminescence, Luminol, Catalysis, Potassium periodate, Triethanolamine (TEA)
