Supplementary file - Sorption of pyrene and fluoranthene onto common microplastics under freshwater conditions

This supplementary file contains detailed descriptions of the materials and experimental methodologies used in a study on the Sorption of pyrene and fluoranthene onto common microplastics under freshwater conditions. It includes comprehensive results from the thermal, morphological, and spectroscopic characterisation of the microplastics, as well as the procedures employed for fitting sorption isotherm and kinetic models. Full datasets and regression analyses are also presented. Additionally, the file contains the derivation and implementation of explicit equations used to solve Fick’s second law for spherical particles.
