Conventional heterogeneous Fenton-like systems employing different peroxides have been developed for water/wastewater remediation. However, a large population of consumed during various with low utilization efficiency and associated secondary contamination become the bottlenecks their actual applications. Recent strategies lowering peroxide consumptions to develop economic are primarily devoted effective radical generation subsequent high-efficiency through catalysts/systems engineering, leveraging emerging nonradical oxidation pathways higher selectivity longer life reactive intermediate, as well reactor designs promoting mass transfer decomposition improve yield radicals/nonradicals. comparative review summarizing mechanisms these has not yet published. In this review, we endeavor showcase designated achieving reduction while ensuring high catalytic activity from perspective above strategic mechanisms. An in-depth understanding aspects will help elucidate key consumption. Finally, existing problems put forward, new ideas research directions consumption proposed promote application in wastewater purification.

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.

Heterogeneous catalyst-mediated sulfate radical-based advanced oxidation processes (SR-AOPs) showed excellent performance during antibiotics degradation. Spinel was a promising catalyst for SR-AOPs, but the secondary contamination due to metal ions leaching needed be addressed. And destruction of structure could lead reduction catalytic activity and difficulty recovery. Thus, novel nitrogen-doped carbon (NC)-supported CoFe

The valorization of Chinese medicine residues (CMRs) into high-value-added products, such as microcrystalline cellulose (MCC), has garnered significant interest in the current post-pandemic era, particularly regions where (CM) is widely utilized (i.e., Southeast Asia). In this study, we propose a facile and economical protocol for selectively extracting MCC from CMRs via one-step direct peroxymonosulfate (PMS) oxidation without need intricate steps. Importantly, our proposed been verified to be versatile can applied various solid waste sources rich cellulose, with an average extraction rate 75%. Analysis using Fukui index revealed that β-O-4 bond, aromatic ring lignin, specific O sites hemicellulose, amorphous region are more susceptible electrophilic attack by PMS than reactions involving HO•, SO4•−, or 1O2. Leveraging distinct mechanism, extracted demonstrated ultrahigh purity (∼95%) crystallinity (∼85.36%). Overall, work involves transforming high-value products through provision technical solution, potential onsite application. This represents advancement CMRs, providing theoretical guidance accelerating recycling materials.
