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 a… Web12 Feb 2002 · A bismuth-film electrode (BiFE) operated in the constant-current potentiometric stripping mode exhibits an attractive performance for trace heavy metal detection. The BiFEs are prepared in situ on a glassy-carbon supporting electrode from the 0.1 M acetate buffer solution (pH 4.5) containing 500 μg/L of bismuth(III) together with …

WebThe method, which is based on potentiometric stripping analysis, is accurate, reproducible and requires little or no sample pre-treatment. Tin causes positive interference in the stripping signal. This interference effect can be reversed for up to 50 mg dm –3 of tin by the addition of 1 mg dm –3 of copper.
