Abstract

In this work, a method for direct lead determination in wine, without wet or dry sample attack, by lead hydride generation-atomic absorption spectrometry, is proposed. To do this, ammonium persulphate is employed as the oxidizing agent, and sodium borohydride is used as the reducing agent. The pH value must be 1.0. Lead content in wine is determined by the analyte addition technique, and the result is compared with those obtained by three different methods. © 1989 Springer-Verlag.
