Sažetak
Microparticles of sediment are mechanically transferred to the graphite electrode surface and the presence of manganese oxyhydroxides is detected by square-wave voltammetry in 0.1 M oxalic acid. After preelectrolysis at -2 V vs. Ag/AgCl, a characteristic stripping peak appears at -0.60 V. Following oxidation at 0.9 V, the response is dominated by a peak at 0.32 V.
