Bisphenol-S (BS) has recently raised public concerns for its adverse effect on the health safety and ecological security. BS concentrations were detected in many water resources, ranging from 10 ng L⁻¹ to 300 μg L⁻¹, so that various purification techniques have been sought to remove BS. This study investigated the performance of ozonation and ferrate oxidation in the degradation of BS since they are both promising oxidants with high redox potential among water treatment chemicals. It was observed that both ozone and ferrate can achieve over 99% of BS concentration reduction and up to 22.5% of DOC reduction for dosing 0.036 mM of either ferrate or ozone. The vibrio fisheri toxicity exhibited a decline in the treated samples after ozonation or ferrate oxidation. According to the mass spectra analyzed, the degradation pathways were proposed and oxidation products (OPs) were identified. BS degradation by ozonation and ferrate oxidation followed a similar route and four common OPs (OP-249; OP-497-a; OP-497-b, and OP-201) were detected. While ferrate treatment produced one more intermediate (OP-217), ozonation did not, which is attributed to the intensified decomposition of BS by ozonation. The major impact of this study is that ferrate treatment is comparable to the ozonation in removing BS, and further research continuing from this study is necessary to explore the BS removal in various waters with more complex matrixes (e.g., high natural organic matter contents), to investigate BS degradation mechanisms in depth, and to conduct pilot-scale and full-scale trials to establish operational database in running ferrate oxidation and/or ozonation for the treatment of BS in practical world.

双酚S（BS）最近因其对健康安全和生态安全的不利影响而引起公众关注。在许多水资源中检测到BS浓度，范围从10 ng L ^-1到300μgL ^-1，因此已寻求各种纯化技术来去除BS。这项研究调查了臭氧降解和高铁酸盐氧化在BS降解中的性能，因为它们都是水处理化学品中具有高氧化还原电势的有前途的氧化剂。观察到，对于0.036mM的高铁酸盐或臭氧，臭氧和高铁酸盐都可以实现超过99％的BS浓度降低和高达22.5％的DOC降低。费氏弧菌在臭氧化或高铁酸盐氧化后，处理后的样品毒性降低。根据分析的质谱图，提出了降解途径并鉴定了氧化产物（OPs）。通过臭氧化和高铁酸盐氧化引起​​的BS降解遵循相似的途径，并且检测到四个常见的OP（OP-249，OP-497-a，OP-497-b和OP-201）。尽管高铁酸盐处理产生了另一种中间体（OP-217），但臭氧化未产生，这归因于臭氧通过臭氧化而增强的分解。这项研究的主要影响是高铁酸盐处理与臭氧处理在去除BS方面具有可比性，因此有必要进行进一步的研究，以探索在基质更复杂（例如天然有机物含量高）的各种水中去除BS的方法，深入研究BS的降解机制，
