Bentonite from locality Me with acid solution at 70 °C for 30 minutes (MDA). Other sample was obtained by impregnation of MDA with nickel acetylacetonate followed by thermal degradation of salt (MDA/Ni(acac)2). The obtained materials were characterized using X-ray diffraction, EPR spectroscopy and low temperature N2 physisorption. The glassy carbon electrode (GCE) was modified using obtained materials and denoted according to these materials. The modified GCE was tested using cyclic voltammetry in 0.1 M H2SO4 aqueous solution containing 10 mM of phenol. A mixture of the hydroquinone and catechol was formed during electrooxidation of phenol. The hydroquinone/ catechol ratio is significant for further application. the goal of this work was to investigate the influence of bentonite modification on current response of GCE modified with these materials, particularly hydroquinone/catechol current ratio. The deconvolution method was used to analyze peaks corresponding to hydroquinone and cate...chol formation during cycling. The chosen deconvolution model excellently fitted experimental data R2=0.9997). Using this model it was found that hydroquinone/catechol current ratio during electrooxidation of phenol increased on Gc modified electrodes in the following order MD<MDA <MDA/Ni(acac)2
