Electrochemical stripping analysis is a set of analytical chemistry methods based on voltammetry or potentiometry that are used for quantitative determination of ions in solution. Stripping voltammetry (anodic, cathodic and adsorptive) have been employed for analysis of organic molecules as well as metal ions. Carbon paste, glassy carbon paste, and glassy carbon electrodes when modified are termed as chemically modified electrodes and have been employed for the analysis of orga… WebIndeed, the major analytical signal in CVS technique is a stripping peak area, and Nickel is well known for its irreversible behavior and passivation at anodic polarization. Complete stripping of nickel from a platinum electrode during CVS cycle can be achieved by introducing of chloride or bromide ions.
