抄録

A new PVC membrane mercury(II) ion electrode based on <i>N</i>,<i>N</i>-dimethylformamide-salicylacylhydrazone (DMFAS) as an ionophore is described, which shows excellent potentiometric response characteristics and displays a linear log[Hg<sup>2+</sup>] <i>versus</i> EMF response over a wide concentration range between 6.2 × 10<sup>-7</sup> and 8.0 × 10<sup>-2</sup> M with a Nerstian slope of 29.6 mV per decade and a detection limit of 5.0 × 10<sup>-7</sup> M. The response time for the electrode is less than 30 s and the electrode can be used for more than 2 months with less than a 2 mV observed divergence in a potentials. The proposed electrode exhibits very good selectivity for mercury(II) ions over many cations in a wide pH range (pH 1 - 4). The electrode was also applied to the determination of a mercury(II) ion in vegetables and in <i>Azolla filiculoides</i>.
