|Title:||Evaluation Of The Degradation Of Sodium Diclofenac Using H 2o2/fenton In Electrochemical Reactor [avaliação Da Degradação Do Diclofenaco Sódico Utilizando H2o2/fenton Em Reator Eletroquímico]|
|Abstract:||This paper describes a degradation study of the anti-inflammatory sodium diclofenac in aqueous medium using an electro-chemical flow reactor with a gas diffusion electrode as cathode. Two degradation processes were compared: by H2O2 electro-generated and H2O2 electro-generated/Fe(II). Concentration of sodium diclofenac was determined during the experiments by HPLC. The changes in chemical oxigen demand (COD) were also evaluated. Under the specific reaction conditions, 350 mg L-1 of H2O2 was electro-generated and 99.2% of sodium diclofenac was degradated, with 27.4% COD reduction. At the same conditions, but using Fe(II), drug degradation was 99.4% and the COD reduction was 63.2%.|
