             abstract = "Copper particles were deposited in the potentiostact mode and 
                         under UV irradiation on the boron doped diamond (BDD) surface. The 
                         copper deposited presented high density and uniformity all over 
                         crystal faces. This behavior may be associated with its 
                         semiconductor character that promoted additional photogenerated 
                         electrons enhancing the copper reduction reaction. This modified 
                         electrode was used as a cathode electrode on the studies of the 
                         nitrates removal from aqueous solutions by electrolysis in an 
                         undivided electrochemical cell and BDD as an anode electrode. The 
                         nitrate reduction was analyzed at three differents initial pH 
                         (neutral, acid and basic). The nitrate reduction rate did not 
                         increase linearly as a function of current densities using 
                         potassium sulphate as the electrolyte (neutral pH). In the present 
                         experiment, the optimum current density was 20 mA/cm2. The nitrate 
                         reduction decreased from 150 to 63.8 ppm. Regarding to the 
                         influence of initial pHs used, it could be conclude that high 
                         value of pH favours the nitrate electroreduction. This result may 
                         be associated with the higher competition between the H+ and the 
                         NO3- ions by electrons on the cathode surface, causing a decrease 
                         in the efficiency of electrolysis.",
