Bisphenol A (4,4-isopropylidenediphenol, BPA) is an organic compound widely used, e.g., in the production of epoxy resins, plastics, and thermal receipt papers. Unfortunately, bisphenol A has negative effects on human health, which has prompted the search for an effective method of its removal. One of the most promising methods of its elimination is photocatalytic removal. The aim of this study was to design an effective method for the photocatalytic removal of bisphenol A using, for the first time, hierarchical zeolites and ruthenium ion-modified diatom biosilica, and silver as photocatalysts and optimization of the reaction conditions: temperature, pH, and composition of the reaction mixture as well as the electromagnetic wavelength. Additionally, for the first time, the electromagnetic wavelength that would be most suitable for the study was selected. All materials used were initially characterized by XRD and low-temperature nitrogen adsorption/desorption isotherms. Ruthenium ion-modified biosilica proved to be the most effective catalyst for bisphenol A removal, which occurred at a rate higher than 99%.
双酚 A（4,4-亚异丙基二苯酚，BPA）是一种广泛使用的有机化合物，例如，用于生产环氧树脂、塑料和热敏收据纸。不幸的是，双酚 A 对人类健康有负面影响，这促使人们寻找一种有效的去除方法。最有前途的去除方法之一是光催化去除。本研究的目的是设计一种使用分级沸石和钌离子修饰的硅藻生物硅首次有效去除双酚 A 的方法，以及作为光催化剂的银，并优化反应条件：温度、pH 值以及反应混合物的组成和电磁波长。此外，首次选择了最适合研究的电磁波长。所有使用的材料最初都通过 XRD 和低温氮吸附/解吸等温线进行了表征。钌离子修饰的生物硅被证明是去除双酚 A 最有效的催化剂，其去除率高于 99%。
