摘要: The removal of sodium ions from aqueous solutions by adsorption onto amorphous carbon thin film (ACTF) has been studied in batch mode. In this work, the ACTF as new adsorbent was synthesized based on rice straw, then its structure and properties were taken into consideration to study ability adsorb synthetic water. influence pH, contact time, temperature ion also using tests. We found that time isothermal described pseudo-second-order kinetic model Langmuir isotherm, respectively. Our results indicated become be stronger depends furthermore, maximum capacities recorded 107, 120 135 mg g−1 at 35, 45, 65 °C. thermodynamic parameters explain is a spontaneous process endothermic reaction. According studies, we can used effectively for chromatography or desalinate exchange hybrid desalination with insignificant loss capacity. However, better than any other materials obtained an agricultural byproduct.
