Five thermodynamic models, namely the modified Apelblat equation, the <em>λh</em> equation, the Non Random Two Liquid (NRTL) equation, the Wilson equation and the Yaws model, were applied to correlate the measured solubility data. The correlation results were evaluated using relative mean deviation (RAD) and root mean square deviation (RMSD). The results indicate that the molar solubility increases with increasing temperature in all sixteen solvents, and all five relevant models can provide satisfactory results. A preliminary evaluation of the potential for chemical bond formation between solute and solvent was conducted by examining the electrostatic potential energy surface of the solute. Density functional theory (DFT) was utilized to calculate the interaction between solute and solvents during the dissolution process. The KAT-LSER model was introduced to analyze solvent effects, and the results showed that hydrogen bond acidity is not conducive to dissolution, while hydrogen bond alkalinity, dipole interaction, and the ability of electron polarization to stabilize charges are conducive to dissolution. The thermodynamic properties of the mixture, such as enthalpy, entropy, and Gibbs free energy, were calculated, and the results showed that the dissolution process of N-fluorobenzenesulfonimide is spontaneous and favorable.</div></div>","PeriodicalId":371,"journal":{"name":"Journal of Molecular Liquids","volume":"428 ","pages":"Article 127526"},"PeriodicalIF":5.3,"publicationDate":"2025-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143791490","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Overall, the toxicity of polyether lubricants greatly influenced by their structures, and it behaves very differently on different organisms.

The ANFIS model was found to be more effective in the prediction of MB sorption to SDPKB than the other models (ANFIS &gt; ANN &gt; RSM), and it was highly applicable in the sorption process. This study has revealed that the SDPKB can serve as a better biosorbent for MB adsorption. Therefore, this study will serve as a first reference point data that will be of great assistance in industrial effluent management as well as decision-making on the adoption of statistical and machine learning models for adsorption study.</div></div>","PeriodicalId":371,"journal":{"name":"Journal of Molecular Liquids","volume":"429 ","pages":"Article 127547"},"PeriodicalIF":5.3,"publicationDate":"2025-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143834977","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
