Abstract

The shortage of water resources in the world and in Iran is always one of the most important human challenges. On the other hand, the existence of large water resources such as seas and oceans, including the Mazandaran Sea in the north and the Persian Gulf in southern Iran, may be one of the most appropriate solutions in this regard. The results showed that total absorption, maximum absorption capacity and percentage of sodium removal for oak leaf and oat leaves adsorbants were equal to 120.21 and 117.10 mg, 1.1 and 0.24 mg / g, 60/10, and 68.88% for concentrations of 5 mg / l 194.45 and 169.93 mg, 1.77 and 0.34 mg / g and 55/56 and 54.82% for concentrations of 10 mg / l and 466.83 and 453.84 mg, 4.26 and 0.91 mg / g, 53.66 and 54.03% for the concentration of 30 mg / ml. The fitting of continuous adsorption models on experimental data by nanostructured adsorbents showed that in the sodium adsorption using fixed bed column for oak leaf and egg shell absorbers, the substrate-time service models, Thomas and Yon-Nelson, respectively, compared to the rest of the models Have better fit of absorption column data. Based on the results of this study, octopus and egg shell nanostructured adsorbents have high potential for removal of sodium ion
