Fig. 1From: Safety assessment of graphene oxide and microcystin-LR complex: a toxicological scenario beyond physical mixtureAdsorption of GO on MCLR physical–chemical characterizations of GO/GO-MCLR. A mixed solution of GO-MCLR (50 μg/mL GO + 1 μg/mL MCLR, pH = 7) was prepared by using the GO and MCLR mother liquors with a concentration of 1 mg/mL. a The adsorption capacity of GO on MCLR after 5 min, 10 min, 30 min, 3 h, 12 h and 24 h were determined. For the pristine GO and the GO-MCLR composite solution when adsorption equilibrium, b TEM analysis of morphology of GO and GO-MCLR; c Raman Spectra analysis of structural defects; d ATR-FTIR/NIR analysis of GO and GO-MCLR functional groups; e XPS quantitative analysis of surface functional groupsBack to article page
