The increasing concentration of carbon dioxide in the atmosphere poses significant challenges for its capture. Carbon dioxide emissions contribute substantially to the greenhouse effect, leading to detrimental effects on ecosystems and drastic climate change. In this study, we synthesized two polymeric Schiff’s bases, by condensing partially oxidized polyvinyl alcohol (OPVA) with 1,2-ethylene diamine and 1,6-hexamethylene diamine. The formed Schiff’s bases are abbreviated OPVA-ED and OPVA-HMD, respectively. OPVA was initially prepared through oxidation of polyvinyl alcohol using potassium permanganate. We investigated the potential of these Schiff’s bases for CO2 adsorption. Structural elucidation of the Schiff’s bases was conducted using Fourier transform infrared (FTIR), 1H nuclear magnetic resonance (NMR), and X-ray diffraction (XRD) techniques…Read more
