A comparison of NaCl transport across two dense cellulosic membranes from different suppliers is presented. Hydraulic and diffusional permeabilities were determined from volume flow-applied pressure and concentration-time relationships, while cation transport number and membrane conductivity were determined from electromotrice force and impedance spectroscopy measurements, respectively. Chemical surface differences between both membranes are correlated to transport parameters and morphology, but differences in elastic properties of both membranes might also be considered in order to get a more complete picture of membrane behaviors and to obtain structural-transport parameters correlations.
本文对来自不同供应商的两种致密纤维素膜的氯化钠传输进行了比较。通过体积流量与施加压力以及浓度与时间的关系来测定水力渗透率和扩散渗透率，而阳离子迁移数和膜电导率则分别通过电动势和阻抗谱测量来确定。两种膜之间的化学表面差异与传输参数和形态相关，但为了更全面地了解膜的行为并获得结构 - 传输参数的相关性，还可能需要考虑两种膜弹性性质的差异。
