Abstract
Phosphonates have received a widespread attention in wastewater treatment due to their potential threat to the water environment. Advanced oxidation processes (AOPs) are feasible methods to degrade phosphonates, and most of the coexisting substances in water show a negative factor during their oxidation. However, the effect of bromide (Br-) on the degradation of phosphonates in peroxymonosulfate (PMS) activation is still unclear. Herein, using 1-hydroxyethane 1,1-diphosphonic acid (HEDP) as a target phosphonate, Br- could remarkably enhance the degradation of HEDP in PMS activation compared to the PMS alone. Under the condition of pH = 7.0, the optimal degradation efficiency of HEDP is 84.8% in the PMS/Br- process after 30-min reaction, whereas no significant oxidation is obtained in the PMS/I- and PMS/Cl- processes. Multiple experiments (i.e., electron paramagnetic resonance (EPR), radical quenching experiments and chemical probs) confirm that free bromine, SO4•- and HO• paly a minor role in HEDP removal, and bromine radical species make a dominant responsible for HEDP oxidation. Additionally, NO3-, SO42-, Cl-, and HCO3- have a little effect on the degradation of HEDP, but the HEDP removal is greatly inhibited in the presence of humic acid (HA). However, the degradation efficiency of HEDP using PMS/Br- process in river and sewage is a much higher than UV/persulfate (PDS) and UV/H2O2 processes. This study provides a new sight into the effect of Br- on the degradation phosphonates in PMS activation process.

Abstract
Reactive oxygen, nitrogen, sulfur, carbonyl, chlorine, bromine, and iodine species (RXS, where X = O, N, S, C, Cl, Br, and I) have important roles in various normal physiological processes and act as essential regulators of cell metabolism; their inherent biological activities govern cell signaling, immune balance, and tissue homeostasis. However, an imbalance between RXS production and consumption will induce the occurrence and development of various diseases. Due to the considerable progress of nanomedicine, a variety of nanosystems that can regulate RXS has been rationally designed and engineered for restoring RXS balance to halt the pathological processes of different diseases. The invention of radical-regulating nanomaterials creates the possibility of intriguing projects for disease treatment and promotes advances in nanomedicine. In this comprehensive review, we summarize, discuss, and highlight very-recent advances in RXS-based nanomedicine for versatile disease treatments. This review particularly focuses on the types and pathological effects of these reactive species and explores the biological effects of RXS-based nanomaterials, accompanied by a discussion and the outlook of the challenges faced and future clinical translations of RXS nanomedicines.

[PMID: 35228029 DOI: 10.1016/j.ecoenv.2022.113340] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/03/2021] [Revised: 02/19/2022] [Accepted: 02/20/2022] [Indexed: 06/14/2023]
Abstract
Thiophenol, which is a highly toxic sulfhydryl compound widely used in chemical industry, is an environmental pollutant that threatens human health significantly. It is of great importance to detect highly toxic thiophenols in both environmental and biological system. Thus, the need to develop rapid response, selective and sensitive probes is urgent. In this study, a novel probe was presented for the detection of thiophenols based on an intramolecular charge transfer (ICT) mechanism. This probe exhibits rapid response, broad pH adaptation (2-10), highly selectivity, a large Stokes shift (131 nm) and 40-fold enhancement in fluorescence. Besides, this probe showed low toxicity towards human cell HEK293 and could be applied to detect thiophenol both in living cells, zebrafish and environmental water samples with good recovery (over 94%). All the results indicated that this probe could be a promising sensor for applications for thiophenol derivatives detection in both environmental and biological sciences.
