title: Reversible pH-independent optical potassium sensor with lipophilic solvatochromic dye transducer on surface modified microporous nylon.
abstract: A reversible and pH-independent fluorescent ion optode is introduced with an ionophore and surface confined solvatochromic dye transducer doped onto microporous nylon membranes. The resulting film responds to K+with excellent selectivity over the range of 10-7to 10-2M and a response time of t95< 60 s above 10-6M.
