Abstract
A two-step procedure including appropriate wet-digestions, separation of selenium from interfering ions such as heavy metal ions with pentyl alcohol and anodic stripping voltammetric (ASV) determination of Pb2+, Cu2+ and SeO32– is developed. The elements in digested whole blood and serum sample solutions were determined by using a standard addition method. 1 × 10–9 mol/L SeO2–3, Cu2+ and Pb2+ were successfully determined with relative standard deviations of approximately 1–2% (n = 6–8).
