摘要：

Electrocoagulation process was used for defluoridation of synthetic fluoride containing water. In the process Mild Steel (MS) was used as sacrificial electrode and experiments were performed with different varying parameters such as pH and current density (CD). The fluoride removal efficiency was found to be maximum at pH 6 and CD 75.44 A/m(2) (2 A). At these conditions fluoride concentration reduces from initial concentration of 50 mg/dm(3) to 5.2 mg/dm(3). Kinetic study of electrocoagulation process revealed that the order of the reaction was in the range 1.61-1.64 with respect to fluoride concentration. It was observed that fluoride removal efficiency of the present MS electrode is comparable to the other electrodes used in electrocoagulation process available in the literature.
