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 60 s accumulation period of 7.4 x 10(-7) M and a sensitivity of 0.24 A M-1. The method was used to evaluate the manganese content of marine sediments taken from Sibenik. Croatia. (C) 2004 Elsevier B.V. All rights reserved.
