吸着速度差を利用した SPR による低分子量イオンの識別

抄録

In this paper we propose a method to identify low molecular weight ions by measuring their absorption speed using intensity interrogation method SPR. We used two ion exchange membranes, Nafion and Flemion, which have different functional groups and show different absorption characteristics to the ions. By measuring the differences in absorption speeds of two membranes, we demonstrated that types and density of 1.7 mM to 34 mM K+, Na+, and Ca2+ ions can be identified.
