Determination of traces of Zn, Cd, Pb and Cu in white sugar by anodic stripping voltammetry and a modified oxygen-flask combustion technique.
Anodic stripping voltammetry with a hanging-drop mercury electrode is used for determination of traces of Zn, Cd, Pb and Cu in white sugar. The sample (1.5 g) is decomposed by ignition in oxygen in a specially modified system.
