Sažetak
A combined approach using solid state electroanalysis (abrasive
stripping voltammetry) and ESR spectroscopy was made to characterize the different species of manganese which are present in
natural and synthetic calcium carbonates. Abrasive stripping voltammetry permits identifying Mn02 and MnC03, but the method
fails when it comes to detecting unambiguously MnC03 in the
presenee of Mn02. Neither can this method detect Mn2+ ions in
mixed crystals of Cal_xMIlxC03because of their low concentrations.
ESR spectroscopy can show that Mn2+ ions are present in
calcite on Ca2+ sites. Additionally, information about the state and
symmetry of Mn2+ site s and the local dynamics of the lattice can
be obtained. In aragonite, only extremely small amounts of individual
Mn2+ ions are present and most of the manganese is found in
the form of Mn02 agglomerates. Solid state electroanalysis and
ESR spectroscopy allow a rather complete qualitative specification
of manganese in calcium carbonates.
