Abstract
The process of turning waste-expanded polystyrene into two distinct anion exchange resins that can be used as absorbents for lead and copper has been studied. In this work, the feasibility of sulfonating polystyrene waste using two techniques—the material's PSS-01 and PSS-02 designations—was investigated. Sulfuric acid is used to form sulfonated functional groups on the polystyrene matrix, which are then used to remove heavy metal ions from wastewater. The improved ion exchange was characterized using FTIR, XRD, and pHPZC. The adsorption kinetics were predicted using pseudo-second-order models. Heavy metal ion exchange studies were conducted in batch mode to determine the kinetic parameters. For copper, PSS-01 had the highest adsorption capabilities at 41.25 g/mg and PSS-03 at 42.1 g/mg.
