Cytotoxicity and Genotoxicity toward Mammalian Cells Induced by Organic Iodine in Peroxymonosulfate (PMS) Processes: Activated PMS Is Better than Nonactivated PMS in Mitigating Toxicity

Environmental Science & Technology, Journal Year: 2025, Volume and Issue: unknown

Published: March 20, 2025

Peroxymonosulfate (PMS) and its activation processes have been extensively studied. However, iodinated byproducts (I-DBPs) generated during nonactivated PMS (NPMS) activated (APMS) pose a significant risk. In NPMS, 50 μg/L concentration of iodide (I–) could significantly (p < 0.05) increase the cytotoxicity both Suwanee River natural organic matter (SRNOM) solution wastewater secondary effluent (SE), at dose 0.5 mM PMS. Cytotoxicity genotoxicity SRNOM increased by 6.6 mg-phenol/L 2.4 μg-4-NQO/L with 200 I–. For toxicities 2.4-fold 1.9-fold. APMS reduced 42–47% 53–60% compared NPMS in I–-containing SE samples. promoted adsorbable iodine (AOI) formation, while inhibited AOI 77.5–84.9%. FTICR-MS showed favored I-DBP generation aromatic precursors, whereas eliminated these precursors I-DBPs. Compounds such as p-iodophenol 4-methyl-2-iodophenol were detected but removed APMS. exhibited weaker oxidation, producing tannic acid-like, lignin-like, protein-like that can toxicity when reacting HOI. Conversely, enhanced oxidation via hydroxyl radicals singlet oxygen, decomposing further. Importantly, also converted HOI into nontoxic iodate, reducing overall water.

Interest in the combination of ferrates and advanced oxidation processes (AOPs) for wastewater treatment has increased, as revealed this systematic review. In study, multiple functions Fe(VI) ferrate-based AOPs are summarized based on Fe species. Various enhanced pathways achieved through electron capture by Fe(VI), Fe(V) Fe(IV), or catalytic effects Fe(III) Fe(II). The different contributions high-valent species general reactive highlighted analyzing results quenching, methyl phenyl sulfoxide probing, paramagnetic resonance analysis. Methods that used to adjust species, including changing reaction pH, oxidant dosage, dosing pattern, addition reducing complexing additives, can influence enhancement efficiency micropollutant from perspective determining transformation Fe(IV) with higher reactivity Fe(II) circulation. Future studies should focus situ production pathway-based adjustments Fe(VI)-AOP techniques.

Insight on the Ultrafast Water Treatment over NiFe-Layered Double Hydroxides via Electroactivation of Ferrate(VI): The Role of Spin State Regulation

Water, Journal Year: 2025, Volume and Issue: 17(9), P. 1369 - 1369

Published: May 1, 2025

Ferrate (Fe(VI)), an emerging green oxidant and disinfectant in water treatment, faces challenges due to its limited reaction efficiency stemming from a highly electron-deficient state. To address this, we designed NiFe-Layered Double Hydroxides (NiFe-LDHs) with different spin states enhance electron transfer Fe(VI)-mediated advanced oxidation processes (AOPs). We hypothesized that fine-tuning the state of NiFe-LDHs could optimize balance between adsorption capabilities electronic structure regulation. Our experiments revealed intermediate-spin NiFeLDH-1, magnetic moment 0.67 μB, exhibited best catalytic performance, achieving 100% phenol removal. The NiFeLDH-x/Fe(VI) system demonstrated significant synergistic enhancement degradation efficiency. In addition, NiFeLDH-1 showed excellent performance stability continuous flow experiments. This study unveils novel correlation polarization efficiency, offering insights into optimization electrocatalysts for AOPs. findings suggest modulation is promising strategy electrocatalytic activity non-noble metal catalysts.
