Copper and bismuth determination at mercury film
carbosital electrode by anodic stripping voltammetry
Abstract
Some
factors have been studied: mercury(II) concentration, composition and
concentration of background, potential and time of mercury formodification of
carbositall disk electrode surface, deposition and regeneration potential Ee (Ereg) and te (treg) of components,
scan rate v etc. Measurement conditions have been optimized and the traces of
copper (II) and bismuth (III) in water samples have been determined. The
determination limits of anodic stripping method (te = 60 s) are 7.10–8 M for copper
(II) and 5.10-8 M for bismuth (III).
