AB  - This paper describes the determination of Pb and Cu with a Nafion-modified glassy carbon electrode and MnCo2O4 nanoparticles as working electrode for anodic stripping voltammetry. Pb and Cu were accumulated in HCl/KCl (0.1 mol dm-3) at a potential of -1.4 V (vs. Ag/AgCl electrode) for 480 s, followed by a linear sweep anodic stripping voltammetry (ASV) scan from -1.0 to +0.5 V. Under optimum conditions, the calibration curves were linear in the range of 0.01 - 8 and 0.01 - 5 mg dm-3 for Pb and Cu, respectively. Effect of sample dilution, accumulation time and potential were optimized. A study of interfering substances was performed. A significant increase in current was obtained at the modified electrode in comparison with the bare glassy carbon electrode. The modified electrode was successfully applied for determination of Pb and Cu in wine samples after a simple preparation procedure. Pb and Cu content in wine was used for estimation of the target hazard quotient (THQ) values for minimal and maximal levels of the metals.

AB  - The porous spinel oxide nanoparticles, MnCo2O4, were synthesized by citrate gel combustion
technique. Morphology, crystallinity and Co/Mn content of modified electrode was characterized
and determined by Fourier transform infra-red spectroscopy (FT-IR), scanning
electron microscopy (SEM), energy dispersive spectrometry (EDS), X-ray diffraction pattern
analysis (XRD), simultaneous thermogravimetry and differential thermal analysis (TG/DTA).
Nanoparticles were used for modification of glassy carbon electrode (GCE) and new sensor
was applied for simultaneous determination of Pb(II) and Cd(II) ions in water samples with
the linear sweep anodic stripping voltammetry (LSASV).The factors such as pH, deposition
potential and deposition time are optimized. Under optimal conditions the wide linear concentration
range from 0.05 to 40 μmol/dm3was obtained for Pb(II), with limit of detection
(LOD) of 8.06 nmol/dm3 and two linear concentration ranges were obtained for Cd(II), from
0.05 to 1.6 μmol/dm3 and from 1.6 to 40 μmol/dm3, with calculated LOD of 7.02 nmol/dm3.
The selectivity of the new sensor was investigated in the presence of interfering ions. The
sensor is stable and it gave reproducible results. The new sensor was succesfully applied
on determination of heavy metals in natural waters.

AB  - This work presents an investigation on spinel structured material that consist of Mn(II) and Co(II) combined in the formula MnCo2O4, where Mn(II) occupies tetrahedral and Co(II) octahedral sites of crystal structure. Such spinel structured material, MnCo2O4 was synthesized by citrate-gel combustion (CGC) technique, carefully chosen as the method of synthesis is very important for producing a material
with desirable physico-chemical characteristics.
