【摘要】 本文利用红外光谱法考察了水与聚苯并咪唑酮(PBIL)膜的相互作用。结果表明:(1)膜中有三种水态存在,即单体水、二聚水和多聚水;(2)三种水态的彼此匹配综合作用使膜有好的盐析效果。同时还对聚苯矾酰胺(PSA)膜进行了粗略的考察,这种膜中也有同样的三种水态存在。更多还原

【Abstract】 Infrared spectroscopy has been used to observe and study theinteraction between water molecules and PBIL reverse osmosismembrane in this paper.The results have showed that:(1)there are three kinds of water states (i.e.water monomer,water dimer and water polymer) in PBIL reverse osmosis membrane;(2)there is no or very weak interaction between water monomerand PBIL membrane.However,there is stronger interaction betweenwater dimer or polymer and the membrane;(3)the excellent desalination of PBIL reverse osmosis membraneresults from the proper combination of these three kinds of waterstates in it.更多还原
