ZnO/AC recovered from PET bottles via pyrolysis for the hybrid treatment (adsorption/photocatalysis) of BB41 dye in aqueous media
Abstract
was recorded for ZnO/AC(PET) due to the pores present on the surface of the activated carbon. After the adsorption step, the treated solutions were further exposed to solar irradiation for a secondary treatment, achieving a removal efficiency of up to 94.44%. The process was optimized by identifying the model that best fits the experimental data and determining the main kinetic mechanism of the photocatalytic degradation of the BB41 dye using first and second-order models. The findings demonstrated that, given the high correlation coefficients, the first-order model offered the best match. This work highlights the valorization of PET waste into ZnO/activated carbon, which shows good affinity for BB41 dye and functions as both an adsorbent and a photocatalyst.
