AB  - The goal of this work was to develop green electrode material that unites all advantages of domestic made, synthesized porous carbon powder and ceria dioxide nanoparticles known due to exceptional catalytic properties. Thermal decomposition of Novolac phenol-formaldehyde resin and cerium sulfate resulting in producing a high-performance CeO2 porous carbon material highly sensitive to dopamine (DA) electrooxidation. Morphological and structural characteristics of the material were determined by SEM and XRD measurements, while electrochemical characterization was performed by EIS and CV. The sensitivity of DA determination on the proposed CeO2-doped carbon material was enhanced by adding multi-wall carbon nanotubes to finally prepare a mixture for a specific carbon paste electrode (TPCeO2&MWCNT@CPE). SWV technique was used for quantification of dopamine in Britton-Robinson buffer pH 6 in the concentration range of 0.5-100 μM of DA, with the detection limit of 0.14 μM and quantification limit of 0.44 μM. Good selectivity overstudied bioactive compounds enables the successful and efficient application of the proposed electrode and developed an analytical procedure for the determination of dopamine in spiked urine samples.

AB  - In this work facile one step synthesis of magnesium ferrite (MgFe2O4) nanoparticles decorated on reduced graphene oxide (MgFe"RGO) using a microwave assisted hydrothermal procedure is reported. The synthesized material was characterized with help of several techniques and applied for the modification of glassy carbon electrode. Such prepared electrode was utilized for successive simultaneous detection of structurally similar compounds, 1,2- and 1,4-dihydroxibenzenes (catechol (CC) and hydroquinone (HQ)), using differential pulse voltammetry technique. It was found that oxidation current increases linearly with the concentrations of both investigated compounds. Detection limits for both species are ≤0.31 μM. The best analytical response in the presence of both CC and HQ, taking into account peak shape and peak current, was obtained at pH 5.6 utilizing acetate buffer solution. The often-presented species in the surface waters as well as gallic acid and caffeine do not interfere with determination of CC and HQ, while ascorbic acid shows high interference. The method is successfully applied for detection of catechol and hydroquinone in real samples analyses. © 2018 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim
