Abstract: Healthy drinking water, free of toxic chemicals and pathogens, is essential for human health. Nitrate ion in water causes human poisoning and is very dangerous. Photocatalytic removal of nitrate from water and conversion to nitrogen gas is of great importance. Heterogeneous nano-catalyst g-C3N4-kaolinite (U-K-1), due to its natural kaolin substrate, has been considered in this study to remove nitrate in the presence of UV light. The results of U-K-1 nanocomposite photocatalyst analysis using FTIR, SEM, EDX and XRD instruments have clearly shown that the surface of the kaolin is covered by urea. The EDX result shows the composition of Al, O, Si, and K in the nanocomposite photocatalyst of 15.03%, 60.42%, 21.23%, and 3.32%, respectively. In this work, the nitrate aqueous solution containing 50 ppm, N Was examined under different conditions. Nitrate removal results showed the highest rate of nitrate degradation and conversion to nitrogen gas (73.15%) in the first 60 minutes.
