Electrochemical incineration of cresols: A comparative study between PbO2 and boron-doped diamond anodes [PDF]

, 2009
The electrooxidation of aqueous solutions containing 5 mM of o-, m- and p-cresol at pH 4.0 has been investigated using a flow filter-press reactor with a boron-doped diamond (BDD) under galvanostatic electrolysis. All cresols are degraded at similar rate
