(a) N2 adsorption-desorption isotherms of GO/CNT, GO/AC, and pure GO membranes. The inset shows the pore size distribution of the GO/AC membrane. (b) UV-Vis absorption spectra of the initial TCH solution and the residue solutions obtained by filtration using GO, GO/CNT, and GO/AC membranes. (c) The saturated adsorption capacity of GO, AC, CNTs, GO/CNT, and GO/AC membranes. EDS images (d) of a cross section of the GO/AC membrane and the corresponding element distribution of (e) carbon, (f) nitrogen, (g) oxygen, (h) silica substrate, and (i) chlorine.
