Abstract

Determination of Mn in synthetic solutions in the concentration range of typical decomposition solutions of Venezuelan laterites showed that a chemical interference from Si and sometimes from Al noted in the air-C₂H₂ flame are eliminated in the N₂O-C₂H₂ flame. A comparison of the determination of Mn in both the air-C₂H₂ and N₂O-C₂H₂ flame by standard-curve atomic-absorption spectroscopy resulted in slightly lower values for the air-C₂H₂ flame, whereas the N₂O-C₂H₂ flame gave values closer to those reported for standard-reference silicates rocks. The reference silicate rocks in the same decomposition solution were also measured by two different colorimetric methods. Finally, Mn was determined in a profile of Venezuelan laterites by atomic absorption in both flames.
