Abstract
The objective of this study is devoted to the elimination of a dye « Black Eriochrome
T » from a synthetic solution by electrochemical way, in particular
electrocoagulation using aluminum electrodes. Different experimental parameters
have been analyzed by this technique are : the initial pH, the distance between the
electrodes, the intensity of the current, the salinity (using the NaCl conductor) and
the dye concentration.
The results obtained made it possible to obtain a discoloration rate of up to 95.23%
for an initial pH equal to 7.08, an electrolysis time corresponding to 60 minutes and
an imposed current equal to 0.1 A, a distance of 1 cm, concentration dye of 20 mg/L
and an amount of NaCl of 3 g/L.
For all these operating conditions, the optimal value of the mass of the dissolved
metal is 0.033 g and that of the energy consumed in this treatment is 0.065 kWh/m³.
