Abstract
The present study recommends the electrocoagulation (EC) technique as a possible-green option to the conventional process for the efficient removal of ibuprofen (IBU) from drinking water for the first time, investigating a thorough analysis by optimizing operational parameters and kinetics/isotherms models. Under the optimum conditions 63% of IBU was removed. The double-stage electrocoagulation resulted in the removal efficiency of 73.8%. The dynamic and equilibrium data followed first-order and Freundlich. The treatment cost of IBU removal by electrocoagulation would be 1.8 US $/m3. It is possible to consider the EC technique as the promising IBU removal method.
