Notes:
Manganese was determined by differential pulse voltammetry in pre-enriched solution. The metal was first deposited on the surface of a hanging mercury drop electrode by electrolysis, and after a short oxidation interval, the reformed manganese(II) ions were determined by differential pulse cathodic polarization scan. The detection limit (with 120 seconds deposition) was 2 μg L-1. The only interfering element was cobalt (when present at tenfold concentration excess). Compared with conventional stripping voltammetry the described method has a lower detection limit value, and the analysis is performed during a shorter time interval. The proposed method was applied for the determination of manganese in natural waters.
