Abstract

A fiber-optic fluorescence sensor for simultaneous two-elemental determinations has been developed. The sensor is based on the formation of a complex between specific metal ions and a metal Ion chelator. Several chelator-ion systems and several means of chelator immobilization were studied. The successful fiber-optic sensor design is based on a pool of chelator solution trapped behind a membrane made of Nafion. The chelator ultimately chosen, lumogallion, forms strongly fluorescent complexes with trivalent aluminum, gallium, and indium ions. Because of the difference in fluorescence lifetimes of the various lumogallion complexes, timeresolved fluorometry enables simultaneous determination of two of these ions.
