To remove NO 2 - from polluted water and wastewater, a selective reduction of nitrite to nitrogen by chemical reduction is a preferable option. Since rehabilitation with NaBH 4, the used PANI-CNTs could be redesigned. The conversion of imine nitrogen and amine nitrogen groups stimulated NO2 reduction and PANI-CNT regeneration. PANI-CNTs delivered an excellent result at NO 2 removal in the presence of competitive ions and in actual water and wastewater samples, demonstrating outstanding results. This latest PANI-CNTs composite may have a lot of potential for water purification and wastewater denitrification.
