Remediation of actual groundwater polluted with nitrate by the catalytic redu…

Abstract. Catalytic reduction of nitrate (NO3-) in groundwater over a Cu–Pd catalyst supported on active carbon was investigated in a gas–liquid co-current flow system at 298 K. Although Cu–Pd/active carbon, in which the Cu/Pdmolar ratio was more than 0.66, showed high activity, high selectivity for the formation of N2 and N2O (98%), and high durability for the reduction of 100 ppm N…
