Abstract

Abstract: To effectively remove bilirubin, amine/methyl bifunctionalized SBA-15 materials (AMS) were directly synthesized by co-condensation of 3-aminopropylmethyldiethoxysilane and tetraethoxysilane using an amphiphilic block copolymer as template under acidic-catalyzed and inorganic-salt-assisted conditions. XRD, N2 sorption analysis, TEM, FTIR and 29Si MAS NMR were used to identify the well-ordered mesostructure and the grafting of amine and methyl groups on the surface of the synthesized materials. The addition of inorganic salt KCl was proven to play an important role in the formation of the highly ordered mesostructure. Increasing KCl concentration from 1.0 to 2.0 M, the morphologies of AMS samples shift from hexagonal platelet to fiberlike morphology. The AMS sample with platelet morphology exhibited faster bilirubin adsorption rate and higher bilirubin adsorption capacity than AMS and pure SBA-15 samples with fiberlike morphology. This could be attributed to the fast molecular transport based on the short mesopore channels and the strong interaction between organic groups (amine and methyl) of AMS and bilirubin molecule.
