Abstract

In this study electrocoagulation EC with hybrid Fe–Al electrodes was used to remove antimony from contaminated surface water Response surface methodology was applied to investigate the interactive effects of the operating parameters on antimony removal and optimize these variables Results showed that the relationship between operating parameters and the response was well described by a secondorder polynomial equation Under the optimal conditions of current density 258 mA/cm2 pH 524 initial concentration 5213 μg/L and time 8917 min more than 99  antimony were removed Besides the antimony adsorption behavior in EC process was also investigated Adsorption kinetics and isotherms studies suggested that the adsorption process followed well the pseudosecondorder kinetic model and the Langmuir adsorption model respectively Adsorption thermodynamics study revealed that the reaction was spontaneous endothermic and thermodynamically favorable These results further proved that the main mechanism involved in antimony removal in EC process could be chemisorption
