AB  - The knowledge of the structural and chemical properties of biochars is decisive for their application as technical products. For this reason, methods for the characterization of biochars that are generally applicable and allow quality control are highly desired. Several methods that have shown potential in other studies were used to investigate two activated carbons and seven biochars from different processes and feedstock. The chars were chosen to cover a wide range of chemical composition and structural properties as a hardness test for the analytical methods used in this study. Specific problems connected with the pretreatment of samples and drawbacks of some methods for some types of chars could be identified in an integrated consideration of the results from different methods. None of the spectroscopic methods was found to be suitable for the quality control of all types of chars. The most valuable results were obtained by chemical analysis that, however, required the complete determination of the main elements, including that of oxygen, and of inorganic components for adequate results. The combination of X-ray photoelectron spectroscopy (XPS) and FT-IR spectroscopy allows a rough characterization of surface functional groups, but cannot discriminate aliphatic and aromatic OH groups. FT-IR might be a suitable method for the quality control of biochars made at lower temperature. The results of Raman spectroscopy did not well correlate with the amount of sp2 hybridized carbon determined by XPS. A better correlation of XPS data was found with the electrical polarization determined by the method of spectral induced polarization that was used for the first time in conjunction with extensive analytical characterization.

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  - The influence of additives (alkyl polyglucoside, Glucopon 600 CS UP and alcohol ethoxylate C18E100) on the behavior of the water/toluene/Lutensol ON 50 (technical oxoalcohol, i-C10E5) microemulsion system as a function of temperature and composition has been investigated. The phase behavior of the microemulsions was determined by vertical sections through the Gibbs phase prism (fish-like phase diagrams). Alkyl polyglucoside shifts the one phase region to lower temperatures compared with water/toluene/Lutensol ON 50 mixtures. This is contrary to the expectation, considering the extreme hydrophilic nature of the sugar headgroup. The addition of hydrophilic alcohol ethoxylate (C18E100) to the water/toluene/Lutensol ON 50 system increases the solubilization capacity of the surfactant, even if the co-surfactant is used in small quantities, and shifts the one-phase region to higher temperature by a few degrees C.
