摘要：

Tin is selectively and simply determined in aqueous solution by measuring the fluorescence produced with oxine-5-sulphonic acid at a pH of 4-5.2 ; intensities are linear from 5 p.p.b. to 0.25 p.p.m. The fluorescence intensity attains a maximum after 10 min and is constant for hours. Few ions interfere and less than 1 p.p.b. can be determined in alcoholic solutions. Fluorescence spectra and intensities are independent of the valence state of the metal. © 1969.
