This computational study analyzes mercury adsorption from wastewater using inversed-vulcanized porous sulfur copolymers. Two inverse-vulcanized sulfur copolymer foams reported previously were selected for this study. These foams were prepared using poly (sodium 4-styrene sulfonate) and sodium chloride as porogens. Mercury adsorption on these copolymer foams was studied and compared to elemental sulfur. Various process parameters were examined, such as mercury-ion concentrations, the volumetric flow rate of wastewater, temperature, and thickness of the adsorbent material. Studying all of these parameters helps optimize the process conditions at high adsorption capacity and predict suitable operational parameters for industrial applications. The CFD model results are validated with the experimental results at fixed and varied operational conditions. The inverse-vulcanized sulfur copolymer foams prepared by using the poly (sodium 4-styrene sulfonate) commoner present high porosity (59.09%), less density (0.53 g/cm 3 ), and smaller particle size (20−50 μm). Therefore, it exhibits high adsorption efficiency in the case of experimental (244 μg/g) and CFD simulations (249 μg/g) compared to other samples.
