Abstract

The efficiency of boron doped diamond (BDD) in the electrochemical
treatment of synthetically contaminated water with veratric acid (VA),
one kind of polyphenolic type compounds, is investigated in this work. A
BDD electrode was practically fabricated using hot filament chemical
vapor deposition (HFCVD). Later on, the BDD electrode was implemented as
an anode in a batch electrolytic reactor. The effect of operating
factors such as the initial concentration of VA, NaCl addition, and
supporting electrolyte type (H2SO4, H3PO4 and Na2SO4)
was studied. The chemical oxygen demand (COD) measurements were
conducted to study the VA electrolysis kinetics. The experimental data
suggested that sodium sulfate was the best supporting electrolyte as the
COD removal reached a percentage of 100% using 1 mmol/dm3 as
VA concentration. The kinetics of the COD decay of the VA electrolysis
were found to obey the pseudo-first order model. Remarkably, the
electrolysis process is significantly speeded up once chloride is added
to the reaction. The complete COD removal was achieved in 60 minutes of
treatment.
