Abstract Solid adsorbent has displayed great application potential in the field of flue gas desulfurization. In this study, using GO as substrate material and the alcoholamines such as ethanolamine (MEA), diethanolamine (DEA) and triethanolamine (TEA) as modifiers, we prepared GO-MEA,GO-DEA and GO-TEA as adsorbents for SO₂, and conducted the characterization by means of scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS), energy dispersive X-ray spectrometry (EDS) and elemental analysis (EA). The SO₂adsorption capacities of the products were also determined by gravimetric method. Our experiment validated the significantly improved SO₂ adsorption capacities of the three types of alcoholamine-immobilized GOs compared to ordinary GO. In particular, GO-DEA exhibits promising adsorption performance toward SO₂, as the equilibrium adsorption capacity within 15 h is 188.5 mg/g initially and 165.3 mg/g after five cycles in which the desorption was processed under vacuum at 130 ℃.
