TL;DR: Benefit from the electron transfer mechanism, the NBC/PDS system not only has wide pH adaptation for real application, but also shows high resistance to the inorganic anions in aquatic environment.

TL;DR: In this paper, sludge-derived biochar (SDBC) was prepared and applied in peroxydisulfate (PDS) activation for sulfamethoxazole (SMX) degradation.

TL;DR: In this paper, peroxymonosulfate (PMS) alone process was systematically demonstrated as nonradical processes for the first time and PMS direct oxidation was firstly verified by the combination of theoretical calculation and experimental detection as well, which were found to selectively degrade sulfonamide antibiotics (SAs) with high efficiency.

TL;DR: In this article, the authors used density functional theory (DFT) calculations and dual descriptor to provide insights into SMT degradation, which indicated that the central cleavages of SMT such as S−N, S−C, and N−C bonds or adducts on the rings would easily occur to degrade SMT in the US/PMS system.

TL;DR: Four possible SMX degradation pathways were accordingly proposed in the Fe0/S(IV)/O2 system based on experimental methods and DFT calculation to reveal special reactive sites on SMX for radicals attacking and predicted intermediates.
