Abstract
Nitrogen in the form of nitrate was electrochemically reduced with different cathode materials including Fe, Ni, Cu, and Zn. Zn cathode shows the greatest electrocatalytic activity on the transformation of nitrate ions into ammonia and the $NO_3^-$ removal efficiency has highest value at pH 8.5. Nitrogen in the form of nitrate was initially reduced into nitrite and sequentially, converted into nitrogen inside $NH_3$. Nitrogen in the form of ammonia was completely removed by the reaction with HOCl.
