The adsorption capacity of a biochar (BC) obtained from pine wood residues was evaluated for its ability to remove two pharmaceuticals: fluoxetine (FLX) and sulfamethizole (SMZ). material showed promising results in FLX removal, but limited the case SMZ. In order improve these results, BC surface modifications were made by doping with nitrogen, as well using acid, basic electrochemical treatments. A three-dimensional electrosorption treatment proved be most effective, increasing rate 0.45 13.46 mg/g after evaluating different operating conditions, such electrodes used or dosage. Consecutive cycles use performed through desorption electro-regeneration techniques test reuse, it observed that application 25 mA electric field increased useful life material. Finally, effect ionic strength studied, highlighting presence ions did not significantly affect efficiency SMZ although slight increase at high ion concentration, probably due salinization effect.
