Abstract

The effect of suspended solid particles on the anodic stripping voltammetric signals of Cu2+, Pb2+, Cd2+ and Zn2+ was studied. In the size range between 2 and 30 µm, inorganic suspended particles do not affect the differential capacity of the electrode. The agitation rate usually used for anodic stripping voltammetry (52.4–261.8 rad s–1) does not promote mass transfer. Therefore, the decrease in the anodic stripping voltammetric peak current intensity can be used to study adsorption on surfaces.
