In this work, the capability of a zeolite Y (FAU-type) and two zeolites beta (BEA-type) to activate peroxymonosulfate (PMS) toward the degradation of one representative pollutant of a pharmaceutical nature (i.e., ciprofloxacin) was tested and compared. Initially, the characterization of the considered zeolites was carried out, evidencing that they had different Si/Al, surface area, and basicity. Then, the main degradation pathway involved in the target pollutant degradation was determined and the activating ability of three zeolites was compared. It was found that among the three tested materials, zeolite Y had the highest activating capability toward PMS for ciprofloxacin degradation (showing ~ 90% degradation after 10 min of treatment). The synergy (S) of the systems followed the order: zeolites beta/PMS (S, 0.5-1.4) < zeolite Y/PMS (S, 3.9), revealing that the Si/Al ratio has a determinant role in the zeolite/peroxymonosulfate combination, being convenient lower values of such a ratio. In the most adequate combination (i.e., zeolite Y/PMS), the pharmaceutical was attacked by singlet oxygen (coming from the PMS activation by the zeolite via basic sites), which modified ciprofloxacin on its piperazyl ring, producing two intermediates. Theoretical analyses based on the structure suggested that the two intermediates have low toxicity against mammals. Additionally, experimental tests showed that the zeolite Y/PMS process led to a resultant solution without antimicrobial activity against S. aureus. Finally, it can be mentioned that ZY/PMS was used to deal with ciprofloxacin in synthetic hospital wastewater, achieving ~ 40% pollutant elimination after 60 min of treatment.</p>","PeriodicalId":545,"journal":{"name":"Environmental Science and Pollution Research","volume":" ","pages":""},"PeriodicalIF":5.8,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143522429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Pulp mill effluents, particularly from Eucalyptus bleached kraft pulp mills, contain phosphorus concentrations that vary with operational conditions. This variability poses challenges for effective treatment and phosphorus removal. However, uncontrolled release of phosphorus-rich wastewaters causes eutrophication. This study focuses on optimizing phosphorus removal from such effluents using cobalt ferrite nanoparticles, with an emphasis on process optimization to address this variability. Minimizing phosphorus concentrations is crucial in wastewater engineering and surface water management. By employing design of experiments and response surface methodology, we aim to fine-tune the phosphorous removal process and pinpoint the key factors with the most significant impact. Optimal conditions for achieving over 90% removal from an effluent with 5 mg P/L were identified as a sorbent dose greater than 1.3 g/L and a pH range between 5 and 7, all within a contact time of only 15 min. For a contact time of 1 and 24 h, the conditions adjust to a sorbent dose greater than 0.97 and 0.83 g/L, respectively, with the pH range remaining the same. Our results highlight the effectiveness of cobalt ferrite nanoparticles as sorbents in the removal of phosphorus for water treatment purposes. This approach presents a sustainable and proficient strategy for phosphorus recovery from pulp mill effluents, thereby lessening environmental repercussions and offering a valuable resource for future use.

As the objective is to eliminate various metal ions (lead, cadmium, and aluminum) from wastewater, we therefore strategically designed and synthesized new iron oxide nanoparticles (Fe₃O₄ NPs) based on the green algae called triiron tetraoxide@algae nanoparticles (Fe₃O₄@Algae NPs) that grow in the same contaminated water using a facile one-pot green synthetic method. Investigations were conducted into the adsorption circumstances, including pH, starting concentration, adsorbent dosage, and adsorption time. More importantly, great absorption of lead, cadmium, and aluminum was achieved, with 97.5%, 81.3%, and 75.13%, respectively. The best conditions were 60 min, 0.1 g of nanoparticles, at 25 °C, and 150 mL of water containing 30 mg/L of Pb, Cd, and Al, with pH 6 for Cd and Pb and pH 5 for Al. To analyze the kinetics and equilibrium adsorption data and to evaluate the interaction between the metal ions and the adsorbent, a variety of kinetic and isotherm models were employed. The Langmuir isotherm and a pseudo-second-order were the best ways to look at the adsorption isotherm and kinetics data for how the Fe₃O₄@algae removes metal ions. Furthermore, thermodynamic studies showed that the adsorption process was an exothermic, favorable, and spontaneous reaction. For the elimination of Al(III), Pb(II), and Cd(II), the Fe₃O₄@algae experimental adsorption capacity was 33.8 mg/g, 56.70 mg/g, and 36.58 mg/g, respectively. The composite of Fe₃O₄@algae nanoparticles was characterized using several analytical techniques including scanning electron microscopy (SEM), energy-dispersive X-ray (EDX), X-ray diffraction (XRD), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), vibrating sample magnetometer (VSM), and UV-vis spectroscopy. In addition, the material exhibited notable durability and recyclability, with the metal removal effectiveness remaining at a high level even after undergoing five successive adsorption cycles.

We discuss various zeolite types (natural, synthetic, and modified) and explore surface modification techniques, including chemical, composite, physical, and biological methods, to enhance fluoride adsorption capacity. Key factors influencing fluoride adsorption, such as pH, temperature, initial concentration, adsorbent dosage, and competing ions, are analyzed. The review elucidates adsorption mechanisms, including electrostatic interactions, ion exchange, Lewis acid-base interactions, and ligand exchange. Adsorption kinetics and isotherms are examined to understand process dynamics and equilibrium behavior. We compare conventional and novel zeolite synthesis methods, highlighting solvent-free approaches for sustainable production. Regeneration potential is assessed, considering environmental impact, cost, and efficiency. While zeolite-based adsorbents show promising results in laboratory settings, we emphasize the need for pilot-scale and full-scale implementations, particularly in treating real industrial wastewater.

The waste rock was leached for 11 weeks before treatment using alkaline silicate solution was applied, without pH buffer and adjuster. One cell was left untreated, whereas the others were treated with silicate solution as a source of dissolved silica, with and without H₂O₂ pre-oxidation. The pH in silica-treated cells generated leachate with circumneutral pH until the end of the leaching cycle, whereas sulfide oxidation accelerated in the absence of treatment. Leachate quality in all Si-treated cells improved, as evidenced by the suppressed release of sulfur and other metals (e.g., Al, Fe, Cu, Co, Mn, and Ni). Upon treatment with a longer contact time, silica (SiO₂) layer developed on waste rock and inhibited pyrite. The layer remained stable upon extended exposure to air and water for up to 10 weeks after treatment. Despite forming a siliceous Fe-O phase, H₂O₂ pre-oxidation resulted in indirect oxidation of sulfides and other phases.

After harvesting, large volumes of waste are generated, often dumped into the environment, contributing to pollution. However, these wastes can be used in the concrete industry to reduce the depletion of mineral resources, thus preventing environmental degradation. This approach supports sustainable development. In this investigation, the effect of pigeon pea stalk ash (PPSA) as a partial cement replacement in concrete was evaluated through a series of experimental tests. The results indicate that compressive strength increases when 4 to 8% of the cement is replaced with PPSA. However, beyond 8% replacement, the strength decreases. Based on the experimental findings, concrete with 8% PPSA demonstrated a 6.96% increase in compressive strength. Further increases in PPSA content led to a reduction in compressive strength. Although the split tensile strength of 8% PPSA concrete was similar to that of the control concrete, it outperformed other replacement levels. Additionally, concrete with 8% PPSA exhibited higher flexural strength compared to the control concrete. PPSA concrete, prepared with up to 8% pigeon pea stalk ash as a cement substitute, also showed reduced permeability and greater resistance to acid attack. All strength and durability test results confirmed that PPSA concrete was superior to control concrete in terms of mechanical properties and durability.
