The potential of microplastics as adsorbents of sodium dodecyl benzene sulfonate and chromium in an aqueous environment

Considering the omnipresence of microplastics (MPs) in aquatic environments, they are expected to exert significatn impacts as carriers for diverse waterborne pollutants. In this work, adsorptive behavior two ionic components (i.e., sodium dodecyl benzene sulfonate (SDBS) and Cr(VI)) has been explored against types MPs model adsorbents, namely poly (ethylene terephthalate) (PET) polystyrene (PS). The influence key variables (e.g., pH, particle size, dose MPs) on their adsorption is evaluated from various respects. maximum capacity values SDBS PET PS estimated be 4.80 4.65 mg?g?1, respectively, while those Cr(VI) ions significantly lower at 0.080 0.072 equilibrium best described relation pH MP size by a Freundlich isotherm. contrast, accounted Langmuir isotherm indicate its across least active surface sites.
