| Description |
The present study describes an electrocoagulation process for the removal of iron
from drinking water using magnesium as the anode and galvanized iron as the cathode.
Experiments were carried out as a function of pH, temperature and current density.
The adsorption capacity was evaluated using both the Langmuir and the Freundlich
isotherm models. The results show that the maximum removal efficiency of
98.4% was achieved at a current density of 0.06 A dm– 2, at a pH of 6.0. The adsorption
of iron was better explained by fitting the Langmuir adsorption isotherm, which suggests
a monolayer coverage of adsorbed molecules. The adsorption process followed a
second-order kinetics model. Temperature studies showed that adsorption was endothermic
and spontaneous in nature.
