Abstract: . The adsorption kinetics followed the pseudo-second-order model, suggesting that chemisorption dominates the process, while isotherm modeling indicated that monolayer adsorption occurred on a homogeneous surface, as described by the Langmuir model. Thermodynamic analysis revealed that the adsorption process was endothermic and spontaneous, confirming enhanced dye-polymer interactions at elevated temperatures. DFT calculations were then applied to provide novel atomistic details that should help in better understanding of the chemical interaction that takes place between the dye and the adsorbent. Furthermore, regeneration studies demonstrated that poly(DVB) was sustainable and can be reused for up to four cycles, supporting its feasibility for real-world wastewater treatment applications. Comparisons with previously reported adsorbents highlighted the superior performance of poly(DVB), making it a promising, adsorbent for dye removal from contaminated water.
