TGA was used to examine the decomposition characteristics of the raw PET. The ultimate, proximate, and Brunauer-Emmett-Teller (BET) analyses of the synthesised PET chars were also used for detailed characterization (Table 1). Furthermore, the dominant processes and the adsorption effectiveness of the investigated PETC-Fe were investigated. In the following sections, the outcomes of all of these have been reported and discussed.
