Abstract

Palmitic acid, a model compound for palm oil mill effluent (POME), was eliminated from a water–ethanol solution using electrochemical oxidation with a boron-doped diamond (BDD) electrode. For a palmitic acid solution in a water–ethanol solution, chronoamperometry with a potential of +3.0 V (vs Ag/AgCl) showed a decrease in chemical oxygen demand (COD) of ~85.75% in 4 h, whereas at a higher potential (+10.0 V), the COD decreased to 75.76% in 1 h. It was noticed that the use of high potentials for up to 4 h caused the structure damaged of the BDD.
