BET, XRD, XPS, SEM, H₂-TPR, TG-DTG, and in situ DRIFTS were adopted to disclose their physicochemical properties and the elimination mechanism of HCHO. 18%Cr_0.5Ce_0.5/WSAC exhibited splendid HCHO abatement efficiency (99.2%) at 280 °C. The effects of O₂, SO₂, H₂O for HCHO abatement over 18%Cr_0.5Ce_0.5/WSAC were trialed, and the strangulation influences of SO₂ counteracted the furtherance effect of O₂ to some extent, which was relieved by the facilitation of H₂O. CrO_x-CeO_x co-facilitated WSAC presented better performance than Cr or Ce oxide separately facilitated WSACs, which was associated with the redox cycle of Cr⁶⁺ + Ce³⁺<b> ↔ </b>Cr³⁺ + Ce⁴⁺, resulting in higher redox capability, better dispersion of active ingredient, more oxygen vacancies and superior active oxygen mobility. Furthermore, the hierarchical porous support accelerated the diffusion and mass transfer of reactants and intermediates. Noteworthily, the effects of CrO_x-CeO_x and the hierarchical porous structure of the support on the tolerance to SO₂ and H₂O were deeply and systematically investigated. Ultimately, 18%Cr_0.5Ce_0.5/WSAC emerged desirable prospects in practical applications thanks to splendid catalytic performance and satisfactory resistance to SO₂ and H₂O.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":"236 5","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143740660","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In most cases, the analytes were extracted only from the receiving phase but recent works show that some compounds were also adsorbed on the PES membranes. Many aspects on the membrane behaviour are still unknown and this work aims to fill some knowledge gaps exploring the capability of PES membranes to adsorb pesticides. From experiments conducted in a controlled environment, it was seen that more than half of the investigated compounds were adsorbed more effectively by the PES membrane than the Oasis HLB phase. The affinity of these pesticides towards the two sampler compartments, can be explained only partially by the polarity of the compounds. However, a significant adsorption of the most hydrophobic compounds by the PES membrane was noticed, especially for values of LogKow higher than 4. From these experiments, it was possible to calibrate POCIS by comparing the pesticide concentration in water with the amount adsorbed by the two sampler compartments over time, with the estimation of two values of sampling rate for each pesticide (<i>R</i>_<i>S,HLB</i> and <i>R</i>_<i>S,PES</i>).

The findings highlighted that industrial-scale application of bioflocculant requires careful control of external factors and optimal operating parameters, such as pH, carbon or nitrogen sources, and cation addition. The interplay between these factors, along with the bioflocculant source, mixing process, and wastewater strength, determine the large-scale applicability of bioflocculant.

Novel research involves biopolymer-based adsorption as the most commonly used remedial method. Herein, a novel psyllium-based polyurethane foam (Psy-PUF) adsorbent was synthesized through polyaddition reaction with 4,4´-Diphenylmethane Diisocyanate (MDI) in the presence of 1,4-diazabicyclo (2.2.2) octane (DABCO 33-LV, as the catalyst), triethanolamine (as the co-catalyst), silicone oil (as a surfactant), and orange peel powder (as a filler) to eliminate dye pollutants. Psy-PUF was characterized using several techniques. The TGA (Thermogravimetric analysis) showed the significant thermal stability of the synthesized Psy-PUF with the final decomposition temperature of 841 °C showing a tremendous increase compared to 601.9 °C for untreated psyllium. Psy-PUF was studied as an adsorbent in binary dye mixtures including cationic and anionic dyes, and the best-adsorbed dyes i.e., malachite green (MG) and crystal violet (CV) were studied. Psy-PUF demonstrated rapid adsorption with 56.38% (MG) and 61.02% (CV) adsorbed only within 20 min, reaching 96.04% and 93.58% for MG and CV, respectively, within 60 min. The adsorption of MG and CV followed pseudo-second-order kinetics with respective R² values of 0.98747 and 0.98685. Moreover, the adsorption behavior of Psy-PUF aligned with the Langmuir isotherm, indicating <i>q</i>_<i>m</i> of 229.35 mg. g⁻¹ for MG and 223.71 mg. g⁻¹ for CV.

The relative abundances of numerous archaeal taxa, such as Euryarchaeota and Woesearchaeota, were markedly higher in soils with the application of mariculture sludge than in those without mariculture sludge treatment, and the taxonomical distribution was significantly correlated with salinity, pH, NH₄⁺, PO₄³⁻ and TN.

The UV–Vis spectroscopy showed the absorption peaks of FeO(B)-NPs and FeO(C)-NPs at 273 and 356 nm, respectively.
