The last decade has witnessed a surge in the development of chemical sorbents cycled through adsorption-desorption processes for CO<sub>2</sub> extraction from low-concentration sources like air (<em>e.g.</em>, Direct Air Capture (DAC)).

Four typical inorganic and organic flocculants (poly aluminum chloride (PAC), poly ferric sulfate (PFS), polyacrylamide (PAM), and modified cationic starch (CS)) were selected for compounding to obtain an optimized flocculation system for high-salt wastewater. The results showed that the PAC-PAM with a 10:1 ratio in mass exhibited the best coagulation behaviors with the removal efficiency of turbidity and chemical oxygen demand (COD) being 95.33% and 9.21%, respectively, under the optimal operation conditions, and the sedimentation process of coagulant conformed to the quasi-second-order kinetics. The PAC-PAM flocs exhibited stronger netting, sweeping, and adsorption bridging capabilities, which were conducive to removing suspended particles. When the flotation was conducted after coagulation, the COD decreased significantly by 20.82%. In addition, this combined process could reduce the treatment time by 50% compared to the process with only coagulation treatment. During the flotation process, floc particles companies with hydrophobic polycyclic aromatic hydrocarbons could collide and adhere to microbubbles and be floated to the surface, resulting in an effective reduction of COD.

Toxicity data of ILs on leukemia rat cell line IPC-81, <em>Escherichia coli</em> (<em>E. coli</em>), and acetylcholinesterase (AChE) were collected from open-source databases, and two integrated models, random forest (RF) and gradient boosted decision tree (GBDT), were used to train the data. The molecular structures of the ILs were represented by three different methods, namely molecular descriptor (MD), molecular fingerprint (MF), and molecular identifier (MI), respectively. The Tanimoto similarity coefficients indicate that MD has a stronger ability to recognize structural similarity. Statistical metrics of model performance showed that the two models (MD-RF and MD-GBDT) with MD as an input feature performed better in the three datasets. The application of the SHapley Additive exPlanations (SHAP) method explains the importance of different features. Specifically, reducing the carbon chain length and the number of fluorine atoms in the structure of ILs can effectively reduce their toxic effects on biological cells.
