It is proved that Fe2S3 nanolayer is successfully loaded on CdS nanorods by TEM and UV-Vis spectra and other means. The representative Rhodamine B was selected as the target pollutant and the results of degradation experiment showed that after 60 minutes of exposure to LED visible light with a low energy (25 W), the removal efficiency for this dye could reach 98% in the presence of peroxymonosulfate (PMS) forming free radicals, which displayed a observed kinetic rate constant exceeding 0.62 min−1 that is approximately 5 times higher than the system without PMS addition and 10 times than the system with original CdS as catalyst. The result of inhibition experiments shows that sulfate radical (SO4·-) and singlet oxygen (1O2) play as important roles during the photocatalytic process. A theory for the reduction is proposed. In addition, this core-shell material can be recycled at least four times. Generally, this study can make full use of visible light which can be easily obtained and effectually resolve the organic pollution problems.","PeriodicalId":11260,"journal":{"name":"Desalination and Water Treatment","volume":"319 1","pages":"100434-100434"},"PeriodicalIF":0.0,"publicationDate":"2024-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147906237","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 order to explore the mechanism and the influencing factors of the adsorption behavior of microplastics (MPs) on selenium (Se) in aqueous solution under the coexistence of nanoparticles, polystyrene microplastics (PS), nano-titanium dioxide particles (TiO2) and their coexisting compounds (PS+TiO2) were used as adsorbents to investigate the adsorption kinetics, isotherms and thermodynamic processes of Se. The effects of pH, humic acid concentration and coexisting ions on the adsorption behavior of Se(VI) were also analyzed. The results showed that the adsorption process of Se(VI) by PS and PS+TiO2 could be well fitted by pseudo-second-order kinetic model and Freundlich isotherm model, and it was an endothermic reaction with increased entropy. The adsorption capacity of Se(VI) by PS, TiO2, and PS+TiO2 were decreased with the increase of solution pH. Humic acid and Ca2+ promoted the adsorption of Se(VI), while PO43- significantly inhibited the adsorption of Se(VI) in the above three systems. The main adsorption mechanism of PS on Se(VI) was electrostatic adsorption and hydrogen bonding. The TiO2 adsorbed on the surface of PS mainly affected the adsorption behavior of PS on Se(VI) through hydrogen bonding.","PeriodicalId":11260,"journal":{"name":"Desalination and Water Treatment","volume":"318 1","pages":"100338-100338"},"PeriodicalIF":0.0,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147900204","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}

For this reason, there is an urgent need to develop nanofiltration membranes with high permeability and selective filtration. In response, a novel composite PVDF loose nanofiltration membrane was developed by combining two different mixed amines system/dopamine (DA) followed by interfacial polymerization with benzoyl chloride (TMC). The two different amines systems were a mixture of GAZ and PEI and a mixture of PIP and PEI, respectively. The effects of GAZ/PEI and PIP/PEI on the microstructure was characterized by SEM, AFM, FTIR and XPS and performance of the membrane was also investigated. The effects of GAZ/PEI and PIP/PEI on the microstructure and the selective layer of membranes were different. The results stated that with the increase of GAZ/PEI the thickness of the selective layer, surface roughness decreased, while the fluxes of pure water and dye wastewater increased. However, with increasing PIP/PEI, surface nodules and roughness both increased. Contrarily, the thickness of the selective layer and PEG800 rejection first decreased and then increased, while the flux of pure water and the dye wastewater first increased and then decreased. The optimal GAZ/PEI and PIP/PEI were 9/91 and 50/50, respectively. When the GAZ/PEI was 9/91, the pure water flux and the RB5 wastewater flux were 20.7 L∙(m2∙h)-1 and 11.5 L∙(m2∙h)-1. The dye (RB5) retention rate was 94.3% and salt retention rate was 2.1%. However, when the PIP/PEI was 50/50, the pure water flux and RB5 wastewater flux were 26.6 L∙(m2∙h)-1 and 17.1 L∙(m2∙h)-1 increased by 87.3% and 134.2% respectively. The retention rates of RB5 and NaCl were 96.3% and 1.7%.

The interaction between Fe3O4/NiO nanoparticles and β-CD molecules was investigated by TGA and FT-IR spectra. The results indicate that β-CD molecules can encapsulate the as-prepared nanoparticles and control the nucleation and growth of Fe3O4/NiO nanocrystals to certain extent. The pyrolysis of β-CD molecules and calcination treatment produced porous structure that provides more adsorption sites for CR molecules. The effect of reaction factors including calcination temperature and pH values was studied to determine the optimum condition. In addition, the thermodynamic and kinetic parameters of CR absorbed on Fe3O4/NiO nanoparticles were measured to understand the adsorption mechanism. The high removal efficiency for CR in aqueous solution was achieved within 60 min of adsorption and 40 min of UV-light irradiation, which can be attributed to the synergistic effect of the adsorption–photodegradation process.

Results showed that sulfate and hydroxyl radicals were the primary active substances in the reaction system, with sulfate radical playing a key role. The addition of CA and Cu2+ improved the efficiency of RhB decomposition, achieving a removal rate of 98.4% after 30 min of reaction, governed by pseudo-first-order. The presence of a complexing agent, allows effective RhB removal over a wide pH range. The free sulfate radical (SO4·−) concentration increases with increasing Fe2+ concentration. However, when the Fe2+ concentration was higher than 0.5 mM, self-quenching of SO4·− occurred and the RhB degradation rate decreased. In contrast, with increasing PDS concentration, the degradation rate of RhB continued to increase. The radical process was the main mechanism of RhB decomposition.

EC parameters were investigated to explore the optimal Boron removal effect of Fe, Al and Fe-Al three combined anodes. Under 46.3–57.2 mA/cm2, 90 min and pH of 9, Fe-Al anodes exhibit the best effect of Boron removal (84% ± 1.5%). Furthermore, high adaptive capacity of low current density and suitable pH confirm the best choice of Fe-Al combined anodes.

Additionally, Eu2O3/BiOBr can be recycled six times without obviously losing catalytic activity.
