In this study, the catalytic properties of Fenton-like catalyst based on magnesium ferrite nanoparticles for IBP degradation were examined. Structural and morphological studies showed the low crystallinity and mesoporous structure for the catalyst obtained via a glycine-nitrate method. The influences of catalyst dosage, oxidant concentration, and solution pH on the pollutant degradation were investigated. The pseudo-first-order model describes kinetic data, and under optimal condition (catalyst dose of 0.5 g L^-1, H₂O₂ concentration of 20.0 mM, and pH of 8.0), apparent rate constant reached 0.091 min^-1. It was shown that Fenton reaction was mainly induced by iron atoms on the catalyst surface, which is supported by very low iron leaching (up to 0.05 mg L^-1) and high catalytic activity at neutral solution pH (6.0-8.0). It was found that the IBP mineralization onto magnesium ferrite catalyst was rapid and reached up to 98-100% within 40 min. Thus, prepared magnesium ferrite nanoparticles can be used as an effective Fenton-like catalyst for the IBP degradation from wastewater.

使用镁铁氧体纳米粒子异质Fenton氧化去除布洛芬的废水：优化和动力学研究

在这项研究中，研究了基于铁氧体镁纳米粒子的Fenton状催化剂对IBP降解的催化性能。结构和形态学研究表明，通过甘氨酸-硝酸盐法获得的催化剂具有较低的结晶度和中孔结构。研究了催化剂用量，氧化剂浓度和溶液pH值对污染物降解的影响。拟一阶模型描述了动力学数据，在最佳条件下（催化剂剂量为0.5 g L ^-1，H ₂ O ₂浓度为20.0 mM，pH为8.0），表观速率常数达到0.091 min ^-1。结果表明，Fenton反应主要是由催化剂表面的铁原子引起的，这是由铁的极低浸出（高达0.05 mg L ^-1）和在中性溶液pH值（6.0-8.0）下的高催化活性所支持的。发现IBP在铁氧体镁催化剂上的矿化作用很快，并且在40分钟内达到了98-100％。因此，制备的铁氧体镁纳米颗粒可用作从废水中降解IBP的有效Fenton类催化剂。
