Abstract

A fluorimetric method for the determination of lithium ion is described in this paper, based on the coordination reaction between 2-(2-hydroxyphenyl)benzoxazole (HPBO) and lithium ion under basic conditions in acetonitrile. The fluorescence intensity is drastically enhanced compared with that of free HPBO upon the addition of lithium ion in the range of 1.0 × 10−7 to 1.0 × 10−4 M, but not for other alkali-metal and alkaline earth metal cations such as Na+, K+, Ca2+ and Mg2+
