| Abstract: | The concentration of lead and cadmium in marine sediments were determined continuously by the standard additions method of the anodic stripping voltammetry after the samples of marine sediments were digestered by nitric acid-perchloric acid-nitric acid.The half wave potential of lead and cadmium during this continuous detection was stable and the peak profiles were symmetric.It was found that the results had good repeatability and high accuracy,and thus this method could be used for the determination of the... |
