Coulometric stripping potentiometry has been used for the quantitative determination of Faradaic reactions on glassy carbon surfaces. Exhaustive cathodic electrolysis in samples (10 L) containing known amounts of Bi III , Cu II , Pb II or Cd II , subsequent stripping of the amalgamated atoms with a
Thc theory of a n improved coulometric stripping potcntiometry method, involving automatic determination of the chemical current for each sample, and thus suitable for calibration-free determination of trace elements in microliter samples is described. The method has been applied to the determinatio
Coulometric stripping potentiometry has been used to achieve calibration-free determinations of Cu(II), Zn(II), Cd(II) and Pb(II) in tap water samples. With the coulometric approach, interference from the formation of Cu-Zn intermetallic compounds (CuZn x ) on the quantification of Zn(II) was circum
The influence of a saturated Triton X-100 layer on gIassy carbon based mercury film electrodes when used for stripping potentiometry determination of mono-, di-and trivalent ions has been investigated. By using an electrode assembly, permitting medium exchange at a controlled potential, it has been
For oxidative stripping potentiometry (OSP) measurement, the achievement of reliable results is highly dependent upon the transport of oxidant to the electrode surface and, as a consequence, careful hydrodynamic control is crucial for reproducibility. Two types of detector system, batch and flow, wi
