Resumen
En este artículo, se discutirá la degradación de los ácidos trans-cinámico y trans-ferúlico a través de procesos electroquímicos de oxidación avanzados (PEOAs) tales como la oxidación anódica con H2O2 electro generado (OA-H2O2), electro-Fenton (EF) y fotoelectro-Fenton (FEF). En un reactor de tanque agitado, a 25 ° C, equipado con un ánodo de 3 cm2 de diamante dopado con boro (BDD) y un cátodo de carbono de difusión de aire de politetrafluoroetileno de 3 cm2, se electrolizó 100 ml de soluciones conteniendo 200 mg L-1 de carbono orgánico total (COT) en Na2SO4 0.05 M a pH 3.0 aplicando densidades de corriente desde 16.67 hasta 100 mA cm-2 durante 360 minutos.
En los experimentos de EF y FEF, se añadió Fe2+ 0.50 mM como catalizador de la reacción de Fenton, mientras que en FEF, la solución se irradió con luz UVA. La capacidad de oxidación de los ácidos con los PEOAs aumentó en secuencia OA-H2O2<EF<FEF para ambos ácidos. Se observó mayor degradación del ácido trans-cinámico durante los PEOAs. A pesar que las moléculas del ácido trans-cinámico y ácido trans-ferúlico, poseen una estructura química similar, éstos se degradaron de forma muy diferente entre sí con los PEOAs aplicados
