Abstract
Abstract The use of synthetic surfactant vesicles as a means for enhancing the photoluminescence of metal chelates is illustrated and a sensitive fluorimetric determination of aluminium with quinolin-8-ol-5-sulphonic acid in vesicles of didodecyldimethylammonium bromide is given. The influence of different variables on the organized aluminium-quinolin-8-ol-5-sulphonic acid reaction is investigated and possible mechanisms of the observed enhancing effects are discussed. The limit of detection is 1 μg l −1 of aluminium. The optimized fluorimetric method has been successfully applied to the determination of aluminium in tap waters and dialysis fluids.
