摘要：
Facilitated transport membranes of poly(vinyl alcohol) containing Ag(I) ions as the carrier were prepared and characterized using ultraviolet-visible spectroscopy (W-Vis), elemental analysis (ICP-AE), scanning electron microscopy (SEM), and SEM(EDXR). Transport experiments were performed using benzene/cyclohexane feed mixtures having volume ratios of 8/2 and 2/8 (v/v). Permeation rates for benzene ranged 0.5-5.5 kg mu m m(-2) h(-1) and benzene/cyclohexane selectivities ranged 51-84, Effects on membrane performance of Ag(I) content, counter ion used, hydration, and degree of cross-linking were investigated.
