Indirect Determination of Manganese in Its Slag by Atomic Fluorescence Spectrometry

A novel method, based on that when the manganese in its slag was enriched and separated by a water soluble polymer, polypropylene, pyrrolidone, the standard As(III), which was added, reduced the manganese In a 0.3 mol/L sulfuric acid Medium, and the excess As(III) was determined on behalf of manganese, is established for indirect determination of manganese by hydride generation-atomic fluorescence spectrometry. Under optimum conditions, manganese content in 0-16 mu g/L Showed a good linear relationship. The detection limit was 0.0091 mu g/mL. The method was applied to determine the manganese in its slag with a satisfactory result.
