Abstract

An indirect voltammetric determination method of thorium based on the displacement reaction between Th (IV) and Zn (II) - EDTA complex in ammonium acetate buffer medium is described. The limit of quantification of 0.005 ppm was observed using differential pulse polarography. The possibly associated metal ions did not interfered in measurements. The method has been successfully applied for the analysis of thorium in waste water samples.
