PRELIMINARY ASSESSMENT OF BISPHENOL A ADSORPTION ON MICROPLASTICS: CAPACITY, EFFICIENCY AND CONTROL FACTORS

In this study, the main focus is on how microplastics (MPs) interact with bisphenol A (BPA) and how this interaction indicates that this is correlated with the polymer and environmental conditions. Each material tested showed a distinct adsorption pattern. Polyethylene (PE) exhibited the highest adsorption capacity at equilibrium. Polystyrene (PS) achieved the highest removal efficiency, while polypropylene (PP) obtained the lowest removal efficiency. BPA binding to MPs may be influenced by hydrophobic interactions, which are accentuated in acidic environments, and contact time, both of that can affect the attainment of equilibrium.
Lastly, this study provided precious insights into the environmental impact of microplastics, which can serve as both a vector for organic compounds, and as a source of pollution.
