摘要：
EDTS-GO nanocomposites were prepared by decorating graphene oxide (GO) with N-(trimethoxysilylpropyl) ethylenediaminetriacetic acid sodium (EDTS). Then EDTS-GO modified PVDF ultrafiltration membrane was prepared by introducing EDTS-GO through blending method. Contact angle results indicated that the hydrophilicity of PVDF membrane was improved owing to introducing EDTS-GO. This was due to EDTS-GO transferring to membrane surface during phase inversion, which was confirmed by FTIR. The effect of the EDTS-GO addition content on membrane property was investigated systematically. With an increase in EDTS-GO content, the water flux of EDTS-GO modified PVDF membrane initially increased and then decreased and reached to maximum of 711.2 L·(m2·h)-1 in the 0.5% content. Furthermore, antifouling experiment demonstrated EDTS-GO modified PVDF ultrafiltration membrane possessed the stronger fouling-resistant performance than pristine PVDF ultrafiltration membrane. © All Right Reserved.
