Název v původním jazyce

IMPROVED FLUORIMETRIC DETERMINATION OF Al, Ga AND In BY MICELLE ENHANCED 8-HYDROXYQUINOLINE -5-SULPHONIC ACID COMPLEX

Popis výsledku v původním jazyce

The enhancement (sensitization) of fluorescent reactions of metal ions with chelating dyes by the presence of surfactants provides an inexpensive alternative to fluorimetric methods, when determination of lower concentrations of elements is required. Thecomplexes formed in micellar media are often characterized by high molar absorptivities, high stability over a wide pH range, and usually by large bathochromic shift caused by addition of surfactants to the binary complex formed in water. Moreover, somefluorescent binary chelates may dramatically increase their quantum yield in micellar media, providing exceptionally sensitive fluorimetric methods. The 8-hydroxyquinoline-5-sulphonic acid (QSA) should provide surfactant-sensitized reactions with Al(III), Ga(III) and In(III), because it is strong acid readily yielding a negatively charged group (sulphonate) to interact with the positive head of cationic surfactants. The importance of monitoring aluminium concentrations in the blood of p
