Abstract

A simple amino-thiacalix4] arene modified graphitic carbon has been prepared by a microwave-irradiation process and employed for the quantification of Hg(II) ions immobilized on screen-printed graphite macroelectrodes (SPEs) as a novel voltammetric sensor. The synthesizedmolecule has been characterized by FT-IR, H-1-NMR and XPS. The proposed sensor exhibits linearity in the range of 2-20 pM with a detection limit of (3s) 1 pM. Furthermore, the modified graphitic material has been used as a sensing platform for the measurement of Hg(II) ions in real samplematrices.
