| Description |
The present study provides an electrocoagulation process for the removal of phosphate from drinking water
using mild steel as the anode and stainless steel as the cathode. The studies were carried out as a function of
pH, temperature, current density, and so forth, and the adsorption capacity was evaluated using both Langmuir
and Freundlich isotherm models. The results showed that the maximum removal efficiency of 98% was achieved
at a current density of 0.05 Aâdm-2 at a pH of 6.5. The adsorption of phosphate preferably fitting the Langmuir
adsorption isotherm suggests monolayer coverage of adsorbed molecules. The adsorption process follows
second-order kinetics. Temperature studies showed that adsorption was endothermic and spontaneous in nature.
