                         manufactured and compared with a standard microcrystalline 
                         commercial electrode, to clarify how their differences may affect 
                         to the production of oxidants in the electrolysis of solutions 
                         containing phosphoric acid or phosphate salts. Effects of the 
                         current density and electrolyte pH were evaluated. Significant 
                         differences were found in the production of oxidants, being the 
                         production of oxidants favored, at high current densities and 
                         alkaline pHs. The effect of the pH was explained in terms of the 
                         higher stability of the peroxodiphosphate anion in comparison with 
                         the monoperox-yphosphate acid produced at low pHs. As well, 
                         because of the improved electrostatic attraction of the anion with 
                         the anode. Despite not exhibiting the largest electrochemical 
                         surface area, the flat UNC electrode shows the best performance 
                         for this process, except for the operation at low current 
                         densities and alkaline pHs in which the porous UNC outperforms it. 
                         Better efficiencies are obtained operating at mild current 
                         densities which was explained in terms of the great significance 
                         of direct processes in the production of oxidants by electrolysis 
                         of phosphoric acid or phosphate solutions.",
