Our main findings demonstrated the effectiveness of a monolayer model with a single-site energy distribution for describing, at the molecular scale, the binding mechanism within biochar pores. By leveraging this framework, we successfully computed the key steric parameters and derived essential thermodynamic functions (molar entropy, molar internal energy, and Gibbs free energy). Thermodynamic analysis revealed that the microscopic docking of hydroquinone onto the adsorbent’s available sites is a spontaneous, endothermic (heat-consuming), and energetically favorable process. Furthermore, the magnitude of the internal energy confirms physisorption, in which weak physical interactions (van der Waals forces) primarily govern surface occupancy.

Structural and morphological characterizations using FTIR, XRD, FESEM/EDX, HRTEM, BET, and TGA confirmed successful grafting, enhanced thermal stability, and the formation of a highly porous, crosslinked architecture. The inclusion of clay significantly improved the hydrogel’s gel content and mechanical integrity, while reducing the swelling ratio due to stronger interfacial interactions. The optimal hydrogel exhibited a BET surface area of 45.6 m2·g−1 and a thermal degradation onset above 300 °C. Adsorption experiments using Safranin T (ST) as a model cationic dye showed rapid uptake kinetics following a pseudo-second-order model (R2 = 0.998), and equilibrium data best fit the Freundlich isotherm (R2 = 0.991), indicating multilayer adsorption on a heterogeneous surface. The maximum adsorption capacity reached 1223.22 mg/g at 25 °C and pH 6. Thermodynamic analysis revealed a spontaneous and endothermic process (ΔH° = 14.8 kJ·mol−1, ΔG° < 0). Density functional theory (DFT) studies supported the involvement of hydrogen bonding, electrostatic attractions, and π–π stacking as dominant adsorption mechanisms.

Transfer properties and interaction coefficients (pair and triplet), along with partial molar expansibility and its temperature derivative, were used to probe structural behavior.
