摘要

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