摘要：
The transport of ions from aqueous solutions through a stacked Au/alpha-Al2O3/gamma-Al2O3/Au membrane under the influence of a dc potential difference is reported. The membrane shows high cation permselectivity at ionic strengths of similar to10(-3) M at pH 4.3-6.5, which is associated with a combination of anion adsorption and double-layer overlap inside the pores of they-alumina layer. The cation flux can be controlled by ionic strength, dc potential difference and pH.
