Abstract
A sodium ion-sensing plate was prepared as an easily-handled ion-sensing optical chemical sensor (optode) probe. The sensing plate consisted of an ion-sensing liquid thin layer containing a Na+-selective neutral ionophore (16-crown-5 derivatives) and a lipophilic anionic dye (KD-A3), which was placed on a chemically modified (octadecyl silanized) frosted glass plate that was covered with a cellulose dialysis membrane. This ion-sensing plate can easily determine Na+ ranging from 10-4 to10-1 M by simply dipping the plate into the sample solution. The response time was ca. 80 s for 10-1 M NaCl with good reproducibility (relative standard deviation (RSD)=±1.33% for ten sequential measurements).
