This study examined the adsorption of CV dye onto PS MPs in aquatic ecosystems. BBD was utilized to optimize adsorption conditions and evaluate the effects of key independent variables on the adsorption process. The sorption experiments were conducted using reaction mixtures containing PS at levels ranging from 0.1 to 1.5 g/L and CV at concentrations of 5 to 20 mg/L. The pH levels of the samples were adjusted to range from 4 to 10, while the duration of interaction varied between 10 and 60 min. The findings revealed that the optimal sorption rate for CV (84.96%) was achieved at a CV level of 12.5 mg/L, a PS dosage of 1 g/L, a pH level of 7, and an interaction duration of 35 min. In this investigation, the ZP of PS particles transitioned from − 45.6 to − 16.8 mV following the sorption of CV. Furthermore, the kinetics of CV sorption were most accurately described by the pseudo-first-order model, demonstrating a high R<sup>2</sup> value of 0.99. The Langmuir isotherm (R<sup>2</sup> = 0.99) further confirmed the presence of significant interactions between the dye molecules and the surface of the sorbent, with the highest sorption capacity quantified at 6.25 mg/g. This study highlights the role of PS microplastics as carriers of harmful dyes, such as CV, in aquatic environments. It underscores the urgent need for further research into the environmental consequences of microplastic pollution and the development of strategies to mitigate their impact.</p></div>","PeriodicalId":8374,"journal":{"name":"Applied Water Science","volume":"15 4","pages":""},"PeriodicalIF":5.7,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13201-025-02418-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143594786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

This event has caused irreparable and serious damage to the agricultural industry in the region, turning this area into a graveyard of date palm trees. Understanding the characteristics of agricultural soils for their improvement and/or planting appropriate plants is one of the goals of sustainable agriculture. Considering the damage of the studied area from the intrusion of salt water in the Arvand River, this study investigated important characteristics of soil salinity including EC, pH, C.E.C, SAR and ESP. In this research, sampling of agricultural soils along the riverside was carried out in three different horizons and two line parallel to the river and at two different distances. Statistical methods of correlation coefficient, hierarchical analysis and factor analysis were used to identify the factors affecting soil quality and the relationships between parameters. The results showed that due to the intrusion of sodium seawater, the soils of the studied area have become saline-sodium, and the salinity level in the soils near the river mouth is higher than that in the soils on the upstream side of the river. In terms of fertility, the cation exchange capacity is in the medium range, and the clay texture and abundant organic matter of the soil as a result of the remaining plant and tree residues have an important effect on this parameter.</p></div>","PeriodicalId":8374,"journal":{"name":"Applied Water Science","volume":"15 4","pages":""},"PeriodicalIF":5.7,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13201-025-02392-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143546359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

The motivation for this study endeavour stemmed from the complex interrelation among nanofluids, magnetic fields and their potential for enhancing heat exchange. A pragmatic numerical approach is utilized to examine the Cu–H<sub>2</sub>O nanofluid flow situation within an enclosure featuring cooled vertical walls and a heat-generating source, while ensuring insulation for the remaining edges. The evaluation analyses the contribution of entropy, including total, viscous and thermal entropies, establishing a connection to real-world heat transfer challenges.

The phenomena of entropy generation, fluid flow and heat transfer are studied under the influence of parameters such as the Hartmann number, Rayleigh number, magnetic field inclination angle and nanoparticle volume fraction. The study reveals that irreversibility increases with the magnetic field inclination angle, while entropy generation decreases with an increase in the Hartmann number. The primary innovation of this study is uncovering new dimensions with widespread practical implications by deciphering the complex dynamics of nanofluid convection with entropy generation and inclined magnetic influence.
