Resumen

Este artículo tiene como objetivo el estudio n estudio comparativo del tratamiento electroquímico de purines generados en rellenos sanitarios realizado con Ánodos Dimensionalmente Estables (ADE) (Ti / Ru0.3Ti0.7O2) y Diamante Dopado con Boro (DDB). A partir de la planificación y control de la capacidad (PCC) se obtuvo el diseño central compuesto rotado (DCCR), cuyas variables independientes en el proceso de electrólisis fueron la densidad de corriente, el tiempo y la concentración de electrolitos. La remoción de Carbono Orgánico Total (variable dependiente) fue 15.40% con densidad de corriente 158 mA cm-², tiempo de electrólisis 15 minutos y 0.2 mol L-1 del electrolito NaCl usando ADE. Con el DDB, en el punto óptimo a 82 mA cm-², 18,5 minutos y 0,19 mol L-1, se verificó la eliminación del 77% de la carga orgánica y la decoloración de aproximadamente el 40% Ultravioleta-Visible.
