Simultaneous determinations of metal 5-sulfo-8-quinolinolates by differences in their fluorescence lifetimes

Add time:08/30/2019    Source:sciencedirect.com

Fluorescence lifetimes of aluminium, gallium, indium, magnesium, zinc, and cadmium 5-sulfo-8-quinolinolates are reported. A method for the simultaneous determination of two components based on the difference in their fluorescence lifetimes is given. The method is applied to determinations of aluminium in magnesium alloy and of magnesium in aluminium alloy. The procedure is simple and rapid, and gives accurate results.
