Interaction of hexavalent chromium and BSCF perovskite in water solutions

In this study, interaction of BSCF perovskite and hexavalent chromium in the aqueous solution was followed to provide additional useful insight in chemistry and behavior of this material. Adsorption experiments were carried out systematically by batch experiments to investigate the influence of contact time, temperature and initial concentration of metal ions. The adsorption data obtained were described by the Freundlich and Langmuir adsorption isotherm model. Thermodynamic study of hexavalent chromium adsorption on BSCF perovskite showed that the spontaneous adsorption process will be favored at higher temperatures (from 343 K) depending on the chromium concentration in water.
