Preparation and Characterization of Graphene Oxide / Cellulose Triacetate Forward Osmosis Membranes
College of environmental Science and Engineering, Donghua University, Shanghai 201620, China
Forward osmosis (FO) is an emerging membrane separation technology in environmental and industrial process. This paper presents cellulose triacetate (CTA) membrane containing graphene oxide (GO) nanosheets via blending to enhance membrane performance in forward osmosis (FO) process. GO nanosheets with various loading were added into the casting solution to prepare the modified FO membranes. The prepared membranes were characterized by morphology analysis and permeability measurement. The result showed that the GO nanosheets effectively improved the performance of the CTA membranes. The CTA-0.2GO membrane had the highest water flux, reached 1.5 times as high as that of CTA membrane.
