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.",
