Zusammenfassung

An optical sensor has been developed for continuous determination of nitrate that is based on a polymer-stabilized emulsion system consisting of a hydrogel with entrapped plasticizer droplets. The droplets contain a cationic potential-sensitive fluorescent dye (PSD) located near its surface. The cationic PSD also acts as an anion-exchange catalyst that extracts nitrate out of the aqueous solution ...
