Removal of Cr(III) ions from salt solution by nanofiltration: experimental and modelling analysis
Anna Kowalik-Klimczak , Mariusz Zalewski , Paweł Gierycz
AbstractThe aim of this study was experimental and modelling analysis of the nanofi ltration process used for the removal of chromium(III) ions from salt solution characterized by low pH. The experimental results were interpreted with Donnan and Steric Partitioning Pore (DSP) model based on the extended Nernst-Planck equation. In this model, one of the main parameters, describing retention of ions by the membrane, is pore dielectric constant. In this work, it was identifi ed for various process pressures and feed compositions. The obtained results showed the satisfactory agreement between the experimental and modelling data. It means that the DSP model may be helpful for the monitoring of nanofi ltration process applied for treatment of chromium tannery wastewater.
