Abstract
Oxidation of charcoal with nitric acid or with SeO2/H2O2 produced biochar, the material similar to the Indian black earth of the Amazon region. The Electron paramagnetic resonance (EPR) spectroscopy data indicate that the organic-free radical density of the prepared biochar is greater under the treatment of charcoal with SeO2/H2O2 than with nitric acid. The FTIR and EPR spectroscopy data of the prepared biochar metal ion complexes with VO2+ and Cu2+ indicate oxygen as metal ions ligand atoms.
