Abstract
The influence of humic substances, Triton X-100 and red wine on the deposition and stripping steps in anodic stripping voltammetry and chronopotentiometric stripping analysis (CPSA) of Cu(II) and Pb(II) was investigated. Fulvic acid and Triton X-100 had an impact only on the stripping step; humic acid and red wine influenced both steps. Failure to establish the impact of matrix components on the individual deposition and stripping steps could result in erroneous interpretation of metal ion speciation.
