| Abstract: | Nitrate (NO3-)
contamination of groundwater is a major concern throughout intensive
agricultural areas. In the present laboratory scale study, an electrolytic
reduction method employing copper cathode and insoluble triple mixed oxide
anode was studied for the denitrification of groundwater in a divided cell.
Influence of process parameters such as pH, current density and time were
studied and the optimal conditions of operation were found to be at pH 8, at
0.89 mA/cm2 for 7 h. It is possible to remove nitrate below the
limit of the drinking water standard using this method. The denitrification was
found to follow pseudo first order kinetics with a k value of 0.23 h-1. |
