Three kinds of modified expanded graphite (EG), impregnated with phosphoric acid (H3PO4) (P-EG), impregnated with glucose (G-EG), and impregnated with H3PO4 and glucose (G-P-EG), were prepared under a low temperature (150°C). The adsorption capacity of G-P-EG (Qm=7.016mg/g) is much higher than original expanded graphite (EG Qm=0.423mg/g) and other two kinds of modified expanded graphite (P-EG Qm=0...
