What is it about?
It is a convenient and effcient approach to the removal of organics in slightly acidic aqueous media and compounds studied include phenol, cresol, catechol, quinone, hydroquinone, aniline, oxalic acid and the azo-dye, amaranth

Why is it important?
In general, chemical oxygen demand (COD) can be reduced from 50-500 ppm to below 10 ppm, generally with a current effciency >50%.
Perspectives
A higher rate of treatment could be achieved with the three dimensional electrode either by increasing the size of the reticulated vitreous carbon or applying a more negative potential than ÿ700 mV vs. SCE (or a higher constant current).
