Abstract
Section titled âAbstractâMicro and nanocrystalline diamond electrodes (BDD and BDND, respectively) doped with boron were grown by the CVD (Chemical Vapor Deposition) diamond deposition technique.The electrodes are characterized morphologically, structurally and electrochemically.These BDD and BDND electrodes were used in the study of the electrochemical degradation of the bentazon organic compound previously purified from the commercial herbicide BasagranÂŽ 600 Herbicide [Composition: 3-isopropyl-1H-2,1,3-benzothiadiazin-4 (3H) -one-2,2-dioxide (Bentazon) -600 g/L (60.0 % w/v) and other ingredients -630 g/L (63.0 % w/v)].The results indicated that during the degradation several intermediates are created at the same time as the formation of isosbestic points occurs, indicating that during the degradation there is the formation of acid-base and/or tautomeric balance between the intermediates formed.NDDB electrode was the most effective in the electrolysis process of the organic compound bentazon, presenting 60.14 % of mineralization in the current density of 50 mA.cm -
