The highly selective and sensitive fluorescence detection of Ba2+ among alkali metal and alkaline earth metal cations was successfully achieved in aqueous media by the combination of a novel monoazacryptand type of fluorophore and micelles of Triton X-100.
Fluorometric sensing of alkali metal and alkaline earth metal cations by novel photosensitive monoazacryptand derivatives in aqueous micellar solutions
selective Ba2+ detection among alkalimetal and alkaline earth metalcations. With respect to the selective fluorescent detection of important metalcations (Na+, K+, Mg2+, Ca2+) relevant to living organisms, was found to detect K+ with high selectivity in aqueous micellar solutions of polyoxyethylene(20) sorbitan monostearate (Tween-60). The selectivity for metalcations was mainly dependent on the goodness
