英文摘要	The quantity and quality of water resources in Iran are the most important challenges in the current situation. A study of global indicators shows that if we do not pay attention to solving these problems, many fertile and residential areas will become deserted and uninhabited. On the other hand, the existence of unconventional water resources such as seas and oceans, including the Caspian Sea in the north and the Persian Gulf in the south of Iran, maybe one of the appropriate and cost-effective solutions in this regard. This study aims to investigate and compare sodium removal using a fixed column by microstructured adsorbents of oak leaf and eggshells. The results showed that the total amount of adsorption, maximum adsorption capacity and percentage of sodium removal for oak leaf and eggshell adsorbents were equal to 120.21 and 117.10 mg, 1.1 and 0.24 mg/g and 60.10, respectively. 68.88% for 5 mg/L, 194.45 and 169.93 mg, 1.77 and 0.34 mg/g, 55.56% and 54.82% for 10 mg/L and 466.83, respectively. 453.84 mg, 4.26 and 0.91 mg/g and 53.66% and 54.03% for a concentration of 30 mg/L. Fitting of continuous adsorption models on experimental data by microstructured adsorbents showed that in sodium adsorption using a fixed bed column for oak leaf and eggshell adsorbents, bed depth-service time, Thomas and Yoon-Nelson models had a better fit than the adsorption column data compared to other models. Based on the results of this study, the microstructured adsorbents of oak leaf and egg shell have a high ability to remove sodium ions.
