The present review offers a concise overview of polysulfides, focusing on various techniques for synthesizing polymers with high sulfur content through direct elemental sulfur polymerization. These methodologies encompass condensation, ionic, and free radical polymerizations. Of particular interest is the extensively discussed free radical polymerization type known as inverse vulcanization. The report delves into the diverse applications of polysulfides, spanning areas such as lithium−sulfur batteries, self-healing materials, IR imaging technology, energy storage, controlled fertilizer, antimicrobial agents, oil spill remediation, water-soluble polymers, and separation science, specifically in metal removal from wastewater. Polysulfides showcase distinctive properties, including optical, thermoresponsive, mechanical, and electrochemical attributes. However, it is crucial to acknowledge that this field is not without its challenges. The review briefly explores the current challenges and potential future developments associated with polysulfides. Additionally, it provides a cursory examination of the role of simulations, modeling, and artificial intelligence in advancing the understanding and applications of polysulfides.

“…The effect of various physical and chemical parameters on adsorption was not explored in the previous experiments of mercury removal by sulfur-porous copolymers, for instance, the impact of water flow rate, temperature, the concentration of mercury, and porous sulfur copolymer. In this manuscript, we analyze the effects of flow rates, temperature, and concentrations on mercury adsorption through computational fluid dynamics. − Computational fluid dynamics (CFD) is a mathematical tool for analyzing complex problems involving fluid–gas, fluid–solid, and fluid–fluid mixtures. − Different partial differential equations are used to explain the process’s physical perspective to understand the fluid’s dynamics. The primary purpose of the CFD tool is to authentically predict the impact of fluid flows under different conditions (e.g., fluid flow, temperature, concentration, velocity, viscosity, etc.)…”

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.
