用红外差谱技术考察反渗透膜中水态的分布

OBSERVATIONS ON THE DISTRIBUTION OF WATER STATES IN ROMs BY IR DIFFERENTIAL SPECTRA

本文用红外差谱技术考察了几种反渗透膜中水态的分布。结果表明:反渗透膜中三种水态(单体水、二聚水和多聚水)的分布与通常的液体水有显著差别,证实反渗透膜对水有一种分散的能力;不同的反渗透膜对水的分散能力不同,从而有不同的脱盐效果。

In this paper,the distribution of water states in reverse osmosis membranes(ROM_s)has been observed and studied by means of IR differential spectra.The results have showed that the distribution of water states in ROM_s is greatly different from that in usual liquid water(ULW),i.e.each of the ROM_s is able to disperse the dimers and the polymers of ULW into monomers,and the dispersing ability of the ROM_s is different from each other.
