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><sub><i>S,HLB</i></sub> and <i>R</i><sub><i>S,PES</i></sub>). It was seen that the combination of the two adsorbent substrates allowed to intercept almost all the studied compounds satisfactorily and this behaviour was also confirmed by a field sampling campaign.</p></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":"https://link.springer.com/content/pdf/10.1007/s11270-025-07901-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143740659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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 R<sup>2</sup> values of 0.98747 and 0.98685. Moreover, the adsorption behavior of Psy-PUF aligned with the Langmuir isotherm, indicating <i>q</i><sub><i>m</i></sub> of 229.35 mg. g<sup>−1</sup> for MG and 223.71 mg. g<sup>−1</sup> for CV.

The results demonstrated that low PFOA concentrations (≤ 0.5 mg/L) enhanced the removal of chemical oxygen demand (COD) and nutrients. However, at concentrations exceeding 0.5 mg/L, COD and phosphate removal efficiencies declined markedly, whereas ammonia nitrogen removal was not significantly inhibited.

High concentrations of PFOA decreased the specific oxygen uptake rate but increased the release of reactive oxygen species (ROS) and lactate dehydrogenase (LDH), collectively impairing microbial metabolic activity.

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