In this study it was aimed to investigate the treatability of cefoperazone with new generation Sb-doped SnO-Ni anodes. For this purpose, it was studied with Sn/Sb/Ni: 500/8/1 anodes for the oxidation of aqueous solution containing cefoperazone antibiotic by addition of different types of electrolyte. Potassium chloride was found as the best electrolyte type affecting the electrochemical reactions positively even at lower concentrations (750 mg/L). At pH 8 the best results were obtained, which is the neutral pH value of the aqueous solution. 50 mA/cm was found as the best value for current density parameter, providing full mineralization just after 60 min of reaction. The removal efficiencies increased generally with the increase of current density, because active oxidants occur increasingly at higher current values. According to the results of the study it was seen that, electrochemical oxidation processes with Sn/Sb/Ni-Ti anodes could be carried out efficiently without need adding extra electrolyte (salt) and pH adjustment step for real wastewaters containing antibiotics. Thus, it was found an easy and economic way to perform electrochemical oxidation with Sn/Sb/Ni-Ti anodes for the wastewaters containing cefoperazone antibiotics.
本研究旨在探讨新型 Sb 掺杂 SnO-Ni 阳极对头孢哌酮的处理能力。为此，研究了 Sn/Sb/Ni:500/8/1 阳极对含有头孢哌酮抗生素的水溶液的氧化作用，通过添加不同类型的电解质进行研究。发现氯化钾是影响电化学反应的最佳电解质类型，即使在较低浓度（750mg/L）下也能产生积极影响。在 pH 值为 8 时获得了最佳结果，这是水溶液的中性 pH 值。发现 50mA/cm 是最佳电流密度参数值，在反应 60 分钟后即可实现完全矿化。去除效率通常随电流密度的增加而增加，因为在更高的电流值下会产生更多的活性氧化剂。根据研究结果，Sn/Sb/Ni-Ti 阳极的电化学氧化过程可以在无需添加额外电解质（盐）和 pH 调节步骤的情况下，有效地对含有抗生素的实际废水进行处理。因此，发现了一种使用 Sn/Sb/Ni-Ti 阳极对含有头孢哌酮抗生素的废水进行电化学氧化的简单且经济的方法。
