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.
