This proposal aims to fabricate a new type graphene oxide (GO) membrane and utilize it to remove dissolved organic matter in water, including optimizing the preparation conditions, evaluating its separation performance and exploring the mechanism. By optimizing the filtration assembly conditions, controlling the interlayer spacing and adjusting the thickness of functional layer, a satisfied GO membrane with high flux and selectivity could be developed. In addition, the micro-interface action process of organic matter on the GO functional layer might be revealed according to the sieving results and adsorption-desorption studies of GO membrane for dissolved organic matter removal. Based on these, we could further understand the theory of GO membrane for contaminant removal in the filtration process, and attempt to develop a new generation membrane to remove the target organic matter in water treatment.
