In this study, a magnetic biodegradable composite of Fe3O4@Zif-8 amine modified@cherry tree gum (FZC) was synthesized to adsorb carbon dioxide (CO2) which was shown in Scheme 1. In order to synthesize FZC, the in-situ and ship-in-bottle methods were utilized to reduce exposure and contamination risks, enable easy reaction scale-up, and improve safety. The inclusion of cherry tree gum in the magnetic composite increased the number of active sites and therefore enhanced its CO2 absorption capacity due to the gum's high surface area. The composite exhibits excellent magnetic properties owing to the presence of Fe3O4, which enables its efficient separation using an external magnetic field. Various analyses were conducted to characterize FZC, and it was found that its CO2 capture capacity rose from 0.74 mmol/g to 1.714 mmol/g when the pressure was increased from 0.1 to 0.9 bar while maintaining a constant temperature of 25℃. The higher CO2 absorption capacity of FZC enables the development of more effective carbon capture and storage (MLS) systems, which are crucial for reducing CO2 emissions from industrial processes and power generation. Different isotherms such as Langmuir, Freundlich, Temkin, and Dubinin-Radushkevich were used to eva‎luate the carbon dioxide absorption efficiency. Overall, this study highlights the potential of FZC composite to capture carbon dioxide from the environment effectively. Its magnetic properties and high surface area make it an ideal candidate for future research.
