利用化学沉积法在聚碳酸酯膜上沉积金，得到的金纳米通道表面带有负电荷，具有亲水性。阿特拉津和百草枯在结构性质上存在差异，百草枯为亲水性分子，水溶液中以阳离子形式存在，而阿特拉津为疏水性分子，水溶液中以分子形式存在，在外加电场的条件下，离子型百草枯由于电泳的作用会发生定向迁移，利用这一特点，实现对两者分子的分离。

Gold nanochannels were prepared by electroless deposition of Au onto the inner wall of porous polycarbonate mem-brane.The surfaces of the as;prepared gold nanochannels are negatively charged and hydrophilic.In aqueous solution,paraquat exists in the hydrophilic cationic form,while atrazine exists in the form of hydrophobic neutral molecule due to their structural difference.Under the applied electric field,paraquat can migrate through the nanotubules due to electrophoresis,resulting in the separation of atrazine and paraquat.
