Abstract
Section titled “Abstract”Abstract The determination of organic and inorganic compounds in a single run is still a great challenge. In this paper, we developed a method for fast simultaneous determination of ascorbic acid (AA) and zinc ions (Zn) using batch injection analysis with detection by square‐wave anodic stripping voltammetry (BIA‐SWASV). Britton‐Robinson (BR) buffer solution (pH=6.0) as the supporting electrolyte and boron doped diamond (BDD) as the working electrode. The method presented favorable analytical characteristics such as fast response (67 injections h −1 ), low detection limits (0.2 and 5.4 μmol L −1 for Zn ions and AA, respectively) and recovery values of 99±3%.
