在目前的研究中，首次证明了使用 Pd@Fe3O4 和混合声电解 (US/EC) 处理系统降解新兴药物微污染物布洛芬 (IBP)。采用共沉淀法合成了磁可分离纳米复合材料 Pd@Fe3O4 催化剂，以提高 US/EC 系统的效率。合成的催化剂即使在使用五次后仍表现出很强的可重复使用性能，并且在所有五次情况下，IBP均保持100%降解。它不仅提高了IBP的降解率，而且使系统的能耗降低了∼35%。其强磁化强度为 64.27 emu g−1，使其易于分离。因此，我们对基于组合能源的 US/EC 系统和磁可分离多功能催化剂在降解布洛芬等难处理污染物方面的应用有了全面的了解，确保 US/EC 可以成为 IBP 治疗的有效选择。
In the present research, the degradation of an emerging pharmaceutical micro-pollutant, Ibuprofen (IBP) by using Pd@Fe3O4and a hybrid sono-electrolytical (US/EC) treatment system has been demonstrated for the first time. The magnetically separable nanocomposite, Pd@Fe3O4catalyst was synthesized following co-precipitation method to enhance the efficiency of US/EC system. The synthesized catalyst showed a strong reusable property even after applying for five times and in all the five cases, 100% degradation of IBP was maintained. It not only enhanced the IBP degradation rate, but also reduced the energy consumption of the system by ∼35%. Its strong magnetization value of 64.27 emu g−1made it easily separable. Hence, a comprehensive knowledge on the application of combined energy based US/EC system and magnetically separable multifunctional catalysts for degradation of intractable pollutants like Ibuprofen was achieved, assuring that US/EC can be an effective option for IBP treatment.
