| Description |
The present study provides an electrochemical coagulation process for the removal of
fluoride from drinking water using a Mg-Al-Zn alloy, magnesium, aluminum and
mild steel as anodes and stainless steel as cathode. Various parameters which may
affect the removal efficiency of fluoride from water, such as pH, concentration of fluoride,
current density, temperature and co-existing ions were studied. Electrochemical
coagulation was carried out for 30 min at an initial fluoride concentration of 5.0 mg/
L and this was reduced to 0.2 mg/L. A maximum removal efficiency of 96% was
achieved with a magnesium alloy as anode and stainless steel as cathode at a current
density of 0.2 A/dm2 and a pH of 7.0.
