    Pertechnetate/Perrhenate Surface Complexation on Bamboo Engineered Biochar

  • Original language description

    The work deals with the evaluation of biochar samples prepared from Phyllostachys Viridiglaucescens bamboo. This evaluation consists of the characterization of prepared materials’ structural properties, batch and dynamic sorption experiments, and potentiometric titrations. The batch technique was focused on obtaining basic sorption data of ⁹⁹ᵐTcO₄⁻ on biochar samples including influence of pH, contact time, and Freundlich isotherm. ReO4-, which has very similar chemical properties to ⁹⁹ᵐTcO₄⁻, was used as a carrier in the experiments. Theoretical modeling of titration curves of biochar samples was based on the application of surface complexation models, namely, so called Chemical Equilibrium Model (CEM) and Ion Exchange Model (IExM). In this case it is assumed that there are two types of surface groups, namely, the so-called layer and edge sites. The dynamic experimental data of sorption curves were fitted by a model based on complementary error function erfc(x).
