双酚被广泛认为是潜在威胁环境和公众健康的有毒化合物。在这里，我们报告使用冷大气压等离子体（CAP）从水系统中去除双酚A（BPA）和双酚S（BPS）。此外，加入甲醇作为自由基清除剂以模拟环境条件。经过480 s的等离子体处理后，15- 25%的BPA仍然存在，而BPS> 80%，BPA的去除速度（-kt= 3.4 ms-1，半衰期= 210 s）比BPS（-kt= 0.15 ms-1，半衰期4700 s）更快。等离子体物种的表征表明，添加自由基清除剂会影响活性氧和氮物种的形成，导致stecOH，H2 O2和NO2-的量较低，但NO3-的量相似。此外，一个非目标的方法，使11 BPA和五BPS转化产品的说明。从这些数据中，提出了这两种化合物的转化途径，表明硝化与进一步的裂解，脱甲基，和羧化，以及较小的双酚中间体的耦合。体外HepG 2细胞模型的毒理学表征表明，CAP过程中形成的转化产物混合物的毒性低于BPA和BPS，表明CAP可有效安全降解双酚。
Bisphenols are widely recognised as toxic compounds that potentially threaten the environment and public health. Here we report the use of cold atmospheric pressure plasma (CAP) to remove bisphenol A (BPA) and bisphenol S (BPS) from aqueous systems. Additionally, methanol was added as a radical scavenger to simulate environmental conditions. After 480 s of plasma treatment, 15–25 % of BPA remained, compared to > 80 % of BPS, with BPA being removed faster (-kt= 3.4 ms−1, half-life = 210 s) than BPS (-kt= 0.15 ms−1, half-life 4700 s). The characterisation of plasma species showed that adding a radical scavenger affects the formation of reactive oxygen and nitrogen species, resulting in a lower amount of ˙OH, H2O2, and NO2-but a similar amount of NO3-. In addition, a non-target approach enabled the elucidation of 11 BPA and five BPS transformation products. From this data, transformation pathways were proposed for both compounds, indicating nitrification with further cleavage, demethylation, and carboxylation, and the coupling of smaller bisphenol intermediates. The toxicological characterisation of the in vitro HepG2 cell model has shown that the mixture of transformation products formed during CAP is less toxic than BPA and BPS, indicating that CAP is effective in safely degrading bisphenols.
