| Abstract: | A flux cell with vitreous carbon tubular electrodes, as auxiliary and working electrodes,
was tested. The following procedure was used: (1) study and optimization of the
mercury deposition conditions at the working electrode, (2) study the electrodes
position and distance in order to minimize dispersion of the sample, (3) study of the
linearity and reproducibility using different concentrations of manganese (2.10-7 to 6.10-
7
M), with differential pulse anodic stripping voltammetry (DPASV) and square wave
stripping voltammetry (SWSV). Good linear correlation was obtained for concentration
of manganese used. |
