Abstract
We have designed new optical membrane sensor which is composed of cell ulose triacetate polymer as a membrane support, o-nitophenyloctyl ethe r as a membrane plasticizer and cyl)(2-hydroxy-5-nitrobenzyloxy)dibenz o-16-crown-5 (1) as a Na+ ion selective chromoionophore. This type of membrane was found to selectively respond to Na+ in the detection limi t of 10(-5) M (1 M = 1 mol dm(-3)) with no significant interference fr om Li+ and K+ ions.
