A novel composite, polyethylene mulch-sorghum straw biochar (Fe-Mo 0.1 /N-PSC), was synthesized via hydrothermal activation, co-impregnation, and high-temperature pyrolysis to enhance catalytic efficiency and facilitate agricultural solid waste valorization. In the Fe-Mo 0.1 /N-PSC/PDS system, this composite efficiently activated PDS, achieving 91.86 % tetracycline (TC) removal within 3 minutes, with a pseudo-first-order rate constant of 0.1426 min⁻¹ , surpassing comparable catalytic systems. The influences of PDS concentration, catalyst dosage, pH, and temperature on TC degradation were systematically investigated. X-ray photoelectron spectroscopy indicated that the reactive Mo 4 + promoted the cycle of Fe²⁺/Fe³ ⁺, accelerating reaction kinetics. Quenching and electron paramagnetic resonance analyses confirmed the generation of radicals (•OH, SO₄•⁻, O₂•⁻), which actively contributed to TC degradation. Additionally, the persistent free radicals derived from PE during hydrothermal activation further enhanced degradation efficiency. Liquid chromatography-mass spectrometry identified degradation intermediates, elucidating possible pathways and proving the toxicity of intermediates greatly reduced. The system exhibited excellent stability, maintaining over 75 % degradation efficiency after five cycles with minimal metal leaching, offering valuable insights for practical applications. This study highlights Fe-Mo 0.1 /N-PSC as an effective PDS catalyst and a sustainable strategy for agricultural waste reutilization. • Fe-Mo 0.1 /N-PSC was prepared to effectively catalyze activation of PDS for organic pollutants degradation. • Mo 4+ effectively improves the cycle of Fe²⁺/Fe³ ⁺ with high non-homogeneous reactivity and minimal metal leaching. • EPFRs generated by PE after hydrothermal activation promote the degradation of TC. • This study offers a novel solution for simultaneously addressing water pollution and solid waste disposal.","PeriodicalId":11260,"journal":{"name":"Desalination and Water Treatment","volume":"322 1","pages":"101158-101158"},"PeriodicalIF":0.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147900742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we synthesized an amine-functionalized hydrotalcite (TEA-Gly-LDH) with a high specific surface area using triethanolamine and glycine, which was employed as an adsorbent for capture phosphate from water. We report the phosphate adsorption properties, isothermal behavior, and adsorption kinetics. The results indicate that TEA-Gly-LDH exhibits a higher adsorption capacity and a faster adsorption rate, achieving equilibrium within 2 hours at 25 °C. The removal rate reached as high as 96 %, with an adsorption capacity of 59.43 mg/g, which is 11 % greater than that of unmodified hydrotalcite. Furthermore, it maintains a high phosphate adsorption capacity across a wide pH range of 3–11. Additionally, TEA-Gly-LDH demonstrates excellent selectivity for phosphate, with a distribution factor of 2.73 × 10 4 in a mixed-ion system, surpassing the 2.39 × 10 3 of unmodified hydrotalcite. The adsorption capacity is preserved even after five regeneration cycles. The adsorption data fit well to the Langmuir isotherm model, suggesting that phosphate adsorption is a monolayer chemisorption process. Kinetic studies reveal that the material's adsorption behavior is primarily governed by ion exchange, adsorption at surface active sites, and intraparticle diffusion. • The preparation and modification of layered double hydroxides using chelating agents and amphoteric ions is proposed. • The specific surface area and active sites of the synthesized materials were significantly enhanced. • The proposed materials exhibited high selectivity and sorption capacity for phosphorus. • The mechanisms of material adsorption primarily involve ion exchange, surface adsorption, and internal diffusion.","PeriodicalId":11260,"journal":{"name":"Desalination and Water Treatment","volume":"322 1","pages":"101138-101138"},"PeriodicalIF":0.0,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147920354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, magnetic chitosan microspheres (MCMs) were prepared by reversed-phase microemulsion cross-linking technology, and the adsorption capacity of MCMs to organic pollutants with high chemical oxygen demand (COD) in coking wastewater was studied. Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM) and energy dispersive spectrometer (EDS), brunauer - emmett - teller (BET), vibrating sample magnetometer (VSM) were characterized. The effects of Fe 3 O 4 magnetic nanoparticles (MNPs), pH and the amount of adsorbent on the adsorption properties of MCMs were investigated. The following conclusions are obtained: the MCMs prepared in this study are successfully encapsulated, and the MCMs have good magnetic properties; Meanwhile, the removal performance of COD is higher. When the addition amount of Fe 3 O 4 is 10 % of the mass fraction of chitosan, the maximum adsorption amount of COD by MCMs can reach 261.82 mg/g under the conditions of pH 7.5, reaction temperature 298 K and adsorption time 42 h. The adsorption kinetics can be described by a quasi-second-order kinetic model. In addition, after 4 times of adsorption-desorption processes, the adsorbent still has more than 40 % COD adsorption, and has good adsorption performance. In general, because of the high adsorption efficiency, strong regeneration and excellent magnetic separation performance, MCMs have practical application potential in sewage treatment, biomedicine and other fields.","PeriodicalId":11260,"journal":{"name":"Desalination and Water Treatment","volume":"321 1","pages":"101020-101020"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147897747","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ozone micro-nano bubble system was compared with the conventional ozone bubble system in terms of initial particle size distribution, liquid phase ozone concentration, free radical generation efficiency, as well as ozone absorption and utilization rates. Furthermore, the elucidation of the degradation pathways for GSM was achieved through rigorous analysis of intermediate product formation. The comprehensive performance of the ozone micro-nano bubble system is better than that of the ozone traditional bubble system. The ozone absorption rate reached 95 % and the ozone utilization rate reached 91.25 % under the ozone micro-nano bubble system. It is worth noting that in pure water, the GSM removal rate of the micro-nano bubble system is 97.11 %. All in all, the ozone micro-nano bubble system can significantly enhance the utilization rate of ozone and improve the removal effect of pollutants.

TEM revealed a nano sheet-like structure for the B-TiO 2 and it exhibited a larger S BET surface area (35.45 m 2 /g) and average pore diameter (5.74 nm) compared to the N-TiO 2 (19.72 m 2 /g) and (2.028 nm) respectively. XPS results showed carbon peaks indicating small bio-carbon doping on the lattice of the TiO 2 , which can promote charge transfer upon light excitation during photocatalyst reactions. The results of the photoluminescence study indicate reduced PL intensity of the B-TiO 2 which signifies the suppression of recombination of charge carriers or electron-hole pairs in the B-TiO 2 . The photocatalytic activity was assessed by the photodegradation of tetracycline (TC: 50 mg/L) under UV irradiation and the B-TiO 2 was employed as a photocatalyst. In the absence of UV light, B-TiO 2 catalyst slightly removed TC due to limited active species. However, the degradation of TC increases significantly due to the synergetic effect of the UV/Fenton/B-TiO 2 hybrid system. Moreover, the biotemplate exposes the surface of the B-TiO 2 which permits improved utilization of all surface-active sites.

A UV/electrochemistry/titanium dioxide (UV/E/TiO 2 ) system was established by coupled membrane filtration. TiO 2 was separated and circulated to remove dimethyl phthalate (DMP). Impacts of catalyst (TiO 2 ), Cl − concentrations, and initial pH on DMP degradation were investigated under different conditions. The results revealed that compared with E and UV/TiO 2 systems, the UV/E/TiO 2 system substantially enhanced the DMP degradation (from 5.11% and 22.54% to 78.33%), with a synergistic factor of 1.16. Radical quenching experiments confirmed that HO· and Cl· were the primary reactive substances for DMP degradation in the UV/E/TiO 2 system. Fluorescence probe experiments, coupled with HPLC and LC–MS analysis, revealed a continuous decrease in Cl − in the UV/E/TiO 2 system due to ongoing photolysis, generating more HO· for DMP degradation in contrast to the E/TiO 2 system.
