However, an atomistic understanding of its underlying adsorption mechanism is still urgently needed because TCDD, given its strong toxicity, requires strict testing conditions in experiments. In this work, a series of grand canonical Monte Carlo (GCMC) simulations were performed to evaluate the effects of the slit width and pore size distribution (PSD) of activated carbons on TCDD adsorption. The microstructural analyses of TCDD within nanoslits demonstrate that when the slit width exceeds 0.8 nm, the orientation of TCDD molecules inclines about 30° along the axis’s normal direction, causing the adsorption amount to increase rapidly. When the slit width exceeds 2.0 nm, its disordered orientation causes the adsorption amount to reach a maximum value. Based on this understanding, we determined the effective specific pore volume (or effective specific surface area) for TCDD adsorption. In combination with the full width at half-maximum (FWHM) of the PSD, we propose the experimentally measurable structural parameter <i>V</i><sub><i>H></i>0.8</sub>/FWHM (or <i>S</i><sub><i>H></i>0.8</sub>/FWHM) and use it as an indicator to reflect the TCDD adsorption performance of different activated carbons.

This study focuses on investigating the efficiency of glycerol extraction from five model biodiesel systems (methyl butyrate, methyl hexanoate, methyl octanoate, methyl decanoate, and methyl laurate) using deep eutectic solvents (DES) based on choline chloride (ChCl)/glycerol and choline chloride/urea (Ur). The influence of DES composition (choline chloride/glycerol) on the separation efficiency was evaluated. Methanol remaining after synthesis was also extracted from the model system using DES. With an increase in the carbon chain length of the ester in the model system, the amount of residual glycerol after synthesis decreases. It was demonstrated that extraction with both DES reduces the amount of glycerol (<0.001 mole fraction) in the model system by an order of magnitude. Additionally, a deficit of glycerol in DES increases extraction efficiency. Repeated extraction allowed complete removal of residual glycerol from all model systems studied. For DES (choline chloride/urea), distribution coefficients for glycerol and methanol were calculated, confirming good separation efficiency.
