[CEST2019_00384] The Effect of Different Parameters on Electrochemical Removal of Ampicillin Using New Generation Sn/Sb/Ni-Ti Anodes
by Kurt A., Yonar T., Helvacioğlu H., Shakir F., Neşelen E.
In this study, it was aimed to investigate the feasibility of new generation and stable Sn/Sb/Ni-Ti anodes for treatment of wastewater containing Ampicillin (AMP) antibiotic by electrochemical oxidation processes. Ampicillin concentration was 0.05 g L-1 in the aqueous solution. Residual ampicillin conc. was measured with Ultra-Performance Liquid Chromatography (UPLC) – Photodiode Array Detector (PDA). While, several parameters were evaluated such salt type and concentration, pH, current density, and anode-cathode distance; salt type and concentration was found as the most effective parameter for the removal of COD, TOC and AMP. Two different type of salts were used for this purpose; sodium chloride (NaCl) and potassium chloride (KCl). However, the removal efficiencies were found more higher in the presence of potassium chloride (KCl) when compared to sodium chloride (NaCl), generally. In the presence of KCl, ≥99% removal of COD and AMP after 60 min, pH 8, 50 mA/cm2, 750 mg/L and 1cm distance between anodes. However, in the presence of sodium chloride (NaCl), complete removal of COD and AMP after 90 min, pH 8, 50 mA cm-2, 2500 mg/L and 1cm distance between anodes.
