11. Electrochemical treatments
INTRODUCTION
Electrochemical treatments
ELECTROCHEMICAL METHODS
Electrocoagulation
Reduction
Oxidation
Direct
Indirect oxidation
With active chlorine
Without UV radiation
With UV radiation:
posterior
Electro-Fenton
Photo-assisted
Photo-Fenton
Heterogeneous photo-catalysis
(Oxidation) 2Cl-  Cl2 (aq) + 2e-
(Reduction) 2H2O + 2e-  2OH- + H2
(Hydrolysis) Cl2 (aq) + 2OH-  H2O + ClO- + Cl-
(Mineralisation) Dye + ClO-/ Cl2 (aq) dye fragments  CO2 + H2O + Cl-
