| Outline of Final Research Achievements |
Graphene oxide (GO) produced from natural graphite shows excellent mechanical, gas barrier, proton conducting properties. Because of these properties, GO is expected to be introduced into wild field. In this study, we try to produce a metal ion separation membrane using a GO freestanding membrane. As a result, we have successfully tuned the copper ion permeation rate through GO freestanding membrane and found that the layer distance is the key factor that determines ion permeation. Moreover, we achieved to separate lead ion from lead and copper ion mixed solution. The separation mechanism was also explained by layer distance. These results are an important step in the study of the ion permeation properties of GO membranes.
