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 60s accumulation period of 7.4 x 10(-7)M and a sensitivity of 0.24AM(-1). The method was used to evaluate the manganese content of marine sediments taken from Sibenik, Croatia.
对三种用于检测海洋沉积物中锰的不同电分析技术进行了评估。结果表明，原位铋膜修饰硼掺杂金刚石电极上锰的阳极溶出伏安法以及碳糊电极上的阴极溶出伏安法缺乏所需的灵敏度和重现性，而裸硼掺杂金刚石电极上的阴极溶出伏安法显示出可靠且具有选择性，在施加60秒富集时间时检测限为7.4×10⁻⁷M，灵敏度为0.24 A M⁻¹。该方法用于评估从克罗地亚希贝尼克采集的海洋沉积物中的锰含量。
