Characterization by Fourier transform infrared (FT-IR) and nuclear magnetic resonance (NMR) spectroscopies confirmed that chemical modification on the zeolite surface had taken place. Based on sorption equilibrium experiments, the diffusion coefficients of permeates in the membrane were obtained, and the order of the diffusion coefficients of xylene isomers was found to be Do ISSN : 0888-5885 En ligne : http://pubs.acs.org/doi/abs/10.1021/ie100256u [article] Pervaporation separation of xylene isomers by hybrid membranes of PAAS filled with silane - modified zeolite [texte imprimé] / Xin Y.
