In this work glassy carbon electrode (GCE) was modified using previously prepared bentonites.
Modification of bentonite was performed by replacing the exchangeable cations present in the
natural bentonite with selected inorganic and organic cations, i.e. AlFeNi polyoxo cations and
benzyltrimethylammonium (BTMA) cations, respectively. Obtained materials were denoted as
AlFeNi-B and BTMA-B. GCE was modified by applying homogenous dispersion of either
AlFe5Ni5-B or BTMA-B and 10 wt. % carbon black in the original Nafion® solution on the
electrode surface. The modified GCE were tested in the acidic solution of phenolic compounds
(phenol-Ph, 2-nitrophenol-2-NP and 4-nitrophenol-4-NP) by cyclic voltammetry using both single
and three-component solution. The modification of GCE led to significant improvement of the
electrode stability. GCE modified with both AlFeNi-B and BTMA-B exhibited lower sensitivity
toward 4-NP in comparison to Ph and 2-NP indicating improved selectivity of in...vestigated
electrodes. All oxidation peaks registered in each of the single solution, were obtained in the mixt
solution as well. Voltammogram recorded using GCE modified with AlFeNi-B in the mixt solution
exhibited more distinguished voltammetric peaks. These results suggest that AlFeNi-B could be
used as a promising electrode surface modifier for simultaneous detection of the phenol and its
derivatives.
