In recent years, nanotechnology has emerged as one of the most attractive technologies for water treatment. The advantages of using nanomaterials include high surface area, high reactivity, on-site fabrication and high potential for use in water treatment. For this purpose, this research was conducted to study the effect of the application of egg shell nanostructured particles on sodium adsorption efficiency as a discontinuous system. The effect of factors such as pH, adsorbent mass, contact time, input sodium concentration on sodium uptake was tested. The results showed that for the studied adsorbent the equilibrium time was obtained after 30 minutes and the maximum sodium uptake at pH was 5. With increasing the adsorbent mass from 0.3 to 0.5 g, the removal efficiency increased from 83.35 to 92.75%, but with increasing the adsorbent from 0.5 to 1.6 g, the adsorption efficiency remained constant. With increasing the concentration of dissolved sodium (5-120 mg / l), the removal efficiency decreased from 89.01 to 68.01%. Among the synthetic models used, the Freundlich isotherm (RMSE = 0.38 and R2 = 0.99) was more suitable for describing the adsorption process and was more consistent with laboratory data.
