Abstract Diclofenac (DCF) is a nonsteroidal anti-inflammatory drug commonly used in health care, livestock, and pharmaceuticals widely detected surface water environments globally. Here, we reviewed the occurrence characteristics, migration pathways, aquatic toxicity of DCF environments. Asian African populations are exposed to high concentrations (> 8,000 ng L−1). Wastewater discharge, industrial pollution primary factors influencing concentration distribution DCF. can cause acute toxicity, oxidative stress, other toxic effects on organisms. We focused China analyzed ecological risks found low risk south north, as well during rainy season dry season. Finally, discuss removal methods for propose potential metal-organic frameworks new material replace conventional removal. This study comprehensively reveals status it poses environments, providing reference environmental management

ABSTRACT Chlorinated aromatic chemicals are highly hazardous, transmissible, and bioaccumulative. Developing an economically feasible catalytic method to facilitate the effective removal of chlorinated pollutants is critical for contamination prevention. The current study extensively investigated utilization organic ligands such as citrate (CA) ethylenediaminetetraacetic acid (EDTA) increase Fe(II)‐activated persulfate (PS) 4‐chlorophenol (4‐CP) 3‐chlorobenzoic (3‐CB) degradation in water. decomposition consumption ability PS alone Fe(II)/PS systems 4‐CP 3‐CB was very low because rapid well discontinuous availability Fe(II), which indicates decline Fe(III) Fe(II). But, when using citrate/Fe(II)/PS EDTA/Fe(II)/PS combinations, 78.86%, 75.01% 84.84%, 80.99% within 30 min, respectively. significant enhancement due both ligand‐to‐metal transfer charges process, this increased process rate determination through carrying electrons into EDTA Fe(III), generating In addition, facilitated with efficiently degraded at acidic pH (2.0–6.0) conditions. pseudo‐first‐order kinetics model accurately predicted ligand/Fe(II)/PS systems. percentage increasing Fe(II) concentrations. Moreover, sulfate hydroxyl radicals formed by were identified major reactive oxygen species decomposition. present investigation recommends alternate strategy enhance mechanisms.

Citric acid (CA) and Cu2+ were used to enhance Fe2+-activated persulfate (PDS) for rhodamine B (RhB) oxidative degradation. The effects of PDS concentration, Fe2+ CA pH, common inorganic anions in water on activation RhB degradation investigated. Results showed that sulfate hydroxyl radicals the primary active substances reaction system, with radical playing a key role. addition improved efficiency decomposition, achieving removal rate 98.4% after 30 min reaction, governed by pseudo-first-order. presence complexing agent, allows effective over wide pH range. free (SO4·−) concentration increases increasing concentration. However, when was higher than 0.5 mM, self-quenching SO4·− occurred decreased. In contrast, continued increase. process main mechanism decomposition. Analysis intermediates C–C C–N bond cleavage most likely mode contaminants become small molecules.

This study evaluates, for the first time, effects of UV/PMS and UV/H2O2/PMS processes on degradation sunscreen agents in synthetic natural water matrices compares their effectiveness with more conventional UV/H2O2. Investigations were conducted using a mixture organic UV filters containing 4-methylbenzylidene camphor (4-MBC) 2-ethylhexyl-4-methoxycinnamate. Among investigated UV-driven AOPs, UV/PMS/H2O2 was most effective water, while highest rate observed during EHMC by UV/PMS. The system promoted sulfate radical (68% degradation), hydroxyl contributing approximately 32%, both species contributed equally to system. Vibrio fischeri assay showed an increase inhibition (up 70%) at specific stages UV/H2O2 treatment when applied which further decreased 30%, along fluence progressive degradation. Pseudomonas putida test recorded minor toxicity (<15%) after treatments. Magnetic biochar utilized conjunction AOPs exhibited superior performance eliminating residual contaminants, providing efficient sustainable approach mitigate treatment.
