N2  - Nitrate ions are considered a serious threat to surface and underground water resources due to their high solubility in water. Therefore, it is necessary to remove them from water sources. There are many ways to remove nitrates from water, the simplest of which is to remove them with adsorbents such as zeolites. In this research work, particles of copper oxide and iron oxide were placed on natural clinoptilolite zeolite. The physical and chemical properties of the prepared nanosorbents were investigated by scanning electron microscopy (SEM), X-ray diffraction (XRD), measurement of the specific surface area of ​​the adsorbents by the BET method, and diffuse reflectance spectroscopy (DRS). After choosing the appropriate adsorbent, other operating factors such as adsorbent amount, pollutant concentration, and solution pH were investigated for removal efficiency. The highest nitrate adsorption efficiency was obtained on clinoptilolite zeolite loaded with 5% copper oxide at a pH of about 4 to 9 at low nitrate concentrations and the adsorbent amount was 15 mg per liter.
