This study therefore aims to elucidate impurity-mediated regulation of Polyaluminum Ferric Sulfate (PAFS) structure–performance relationships through comparative synthesis of pure reagent systems (PAFS-C) and red mud acid leachate systems (PAFS-J). Experimental results demonstrate that in PAFS-J, Na⁺ occupies Fe/Al active sites via ion exchange to inhibit hydroxyl bridging, while SiO₂ in calcined red mud transforms into reactive silicic acid, fragmenting polymer structures through Al–O–Si bonding and Si–O–Si networks, leading to significantly inferior flocculation efficiency compared to PAFS-C. The flocculation mechanism of PAFS-J was further investigated through Zeta potential analysis and polarized light microscopy. The results demonstrate that PAFS-J relies on electric double-layer compression and weak charge neutralization to form loose flocs, with its flocculation process following a multi-stage cooperative mechanism involving charge neutralization, adsorption bridging, and sweep flocculation. This study deeply elucidates the inhibition mechanisms of impurities on the flocculation performance of PAFS and their flocculation mechanism, providing a theoretical foundation for the precise design of red mud-based flocculants and the high-value utilization of industrial solid waste.</p></div>","PeriodicalId":666,"journal":{"name":"Journal of Solution Chemistry","volume":"55 7","pages":"1427 - 1450"},"PeriodicalIF":1.3,"publicationDate":"2026-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148466449","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 3069 experimental speed of sound data points were compiled for 22 fatty acid alkyl esters over a temperature range of 278.15–608.15 K and pressures up to 210 MPa. The results show that the model yields average absolute relative deviations (AARD%) of just 0.41% at atmospheric pressure and 1.03% under high-pressure conditions. Also, the proposed correlation, combined with the ideal mixture rule, was applied to predict the speed of sound in 18 biodiesel fuels, achieving an overall deviation of only 0.31%.

Across perovskite, sol–gel, and electrodeposited systems, time-dependent solvent reorganization and interfacial structuring have been shown to directly influence film morphology, defect formation, and functional performance. Despite this growing evidence, solvent effects are still predominantly rationalized using static descriptors such as dielectric constant, polarity, or donor number. These macroscopic averages fail to capture the dynamic, time-dependent processes that govern precursor coordination, nucleation, and crystallization under nonequilibrium conditions. This mini-review consolidates experimental and computational evidence showing that solvent reorganization, interfacial structuring, and fluctuating solvation fields critically shape film morphology and functionality. Time-resolved spectroscopies (SFG, 2D-IR, ultrafast X-ray) and in situ scattering (GIWAXS/GISAXS) reveal femtosecond to second-scale solvent dynamics that steer phase transitions and defect formation in perovskite, sol–gel, and electrodeposited systems.

Gaussian Process (GP) models were implemented to analyze, predict, and validate solubility behavior. The GP model successfully captures salting-in and salting-out trends, along with specific ion effects reported in the literature. It also provides predictive uncertainty estimates that help identify potentially inconsistent data points or sets. This uncertainty-based analysis enables the reconciliation of conflicting datasets and helps prioritize new experimental measurements in regions where data are sparse or less reliable. By applying a data-filtering method that removes experimental points falling outside the uncertainty range of the model, the influence of inconsistent values is reduced. This results in a more robust model fit and improved prediction accuracy.
