Abstract

Transport numbers of sodium, nickel, and lanthanum counterions have been studied in microporous (average pore radius is r = 2–3.4 nm) and macroporous (r = 16–27 nm) magnetite-free glasses and those containing magnetite in their matrices. It has been found that, in the case of microporous glasses, the relation between the transport numbers of the studied cations is primarily governed by the structure of secondary silica in pore channels. For membranes prepared from macroporous glasses, the transport numbers of the cations in the pore space depend on the surface charge magnitude and the structure of the electrical double layer.

多孔玻璃中单电荷、双电荷和三电荷阳离子的传输数

摘要

在微孔（平均孔半径为r = 2-3.4 nm）和大孔 ( r = 16-27 nm) 不含磁铁矿的玻璃和基质中含有磁铁矿的玻璃中，研究了钠、镍和镧反离子的传输数。已经发现，在微孔玻璃的情况下，所研究的阳离子传输数之间的关系主要受孔道中二级二氧化硅的结构控制。对于由大孔玻璃制备的膜，孔隙空间中阳离子的传输数取决于表面电荷的大小和双电层的结构。
