Abstract

A chloride-selective optode is presented which is based on a polymer-stabilized emulsion system which consists of a hydrogel into which plasticizer droplets are incorporated containing a neutral chloride-selective ionophore. A solvatochromic cationic fluorescent dye is located in the hydrogel. When the ionophore extracts chloride out of the aqueous solution into the plasticizer droplets, the ...
