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).
