Fluorimetry of Selected Elements and Substances in Complex and Micellar Media
Original language description
The collinear fluorescence spectra appear for complexes with 8-Hydroxyquinoline-5-sulphonic acid (QSA) with max 495 nm for Al, 504 nm for Ga and In in dependence on pH. The fluorescence is highly increased in the presence of submicellar concentration ofcationic surfactants, especially Zephyramine. The stoichiometry of the components in the complexes is M:L = 1:1 - 1:3 in the absence of surfactant and M:L = 1:3 in the presence of cationic surfactant. The optimal concentration range for the determinationof Al, Ga and In is 0.03 1 g.L-1, the detection limits 0.03-0.04 g.L-1 in the presence or absence of surfactant for normal and first derivative spectra. Fe3+, fluoride, phosphate and excess of nitrate and bromide interfere in the absence and presence ofZephyramine. The first derivative spectra for pH 3, 8 and 4 with max 460 nm for Al, 472 nm for Ga and 478 nm for In do not bring advantages. For the determination of Al, Ga, and In at pH 4, 3, and 8 in the presence of MES or tetraborate
