| 摘 要： | 采用化学沉积法将金沉积到聚碳酸酯膜内孔壁,制备了呈负电性的阵列金纳米通道.在外加恒电压作用下,阳离子型的百草枯选择性通过负电性的金纳米通道,阿特拉津为分子型化合物,不受电荷选择性和电泳作用影响,难以在金纳米通道内迁移.借此,可实现二者的分离.

| Abstract: | The nanotubule negatively charged were prepared by depositing gold onto the walls of pores of polycarbonate membrane using an electroless plating method.Paraquat positively charged can transport through the nanotubule membrane,whereas atrazine,a molecular compounds,is more difficult to transport through the nanotubule negatively charged than paraquat due to the charge selectivity and electrophoresis.Paraquat and atrazine can be separated based on this nanotubule membrane. |
