Abstract
Three different electroanalytical techniques for the detection of manganese in marine sediments are evaluated. The anodic stripping voltammetry of manganese at an in situ bismuth-film-modified boron-doped diamond electrode and cathodic stripping voltammetry at a carbon paste electrode are shown to lack the required sensitivity and reproducibility whereas cathodic stripping voltammetry at a bare boron-doped diamond electrode is shown to be reliable and selective with a limit of detection, from applying a 60Â s accumulation period of 7.4 Ã 10â7Â M and a sensitivity of 0.24Â AÂ Mâ1. The method was used to evaluate the manganese content of marine sediments taken from Å ibenik, Croatia.
