Currently, carbon dioxide (CO2) capture can preserve environmental quality by using carbon- based adsorbent. In this research, Polyethylenehexamine (PEHA) functionalized carbon-based soybean curd residues (carbonized SCR-PEHA) was prepared for CO2 adsorption. Analysis of functional groups of the prepared adsorbent using Fourier Transform Infrared Spectroscopy (FTIR), confirmed the functionalization of PEHA on the carbonized SCR. CO2 uptake of the carbonized SCR-PEHA was compared with the bare SCR using Thermogravimetric Analyzer (TGA) analysis. TGA results revealed that the adsorption capacity of CO2 for carbonized SCR-PEHA and bare SCR are 8.816 mg/g and 3.027 mg/g respectively. It was observed that functionalization of the PEHA on the surface of carbonized SCR had improved the adsorption capacity of CO2 by 2.92 times as compared to bare SCR. The phenomenon can be explained from the interaction of the CO2 with the available amine sites provided for the carbonized SCR-PEHA which significantly improved the CO2 adsorption. Hence, the carbonized SCR-PEHA demonstrate potential adsorbent for CO2. © 2021 Institute of Physics Publishing. All rights reserved.
