A Fluorimetric Study of the Thorium-Morin System
The following report evaluates the fluorescent system of the reaction between morin and thorium in weakly acid solutions in order to form a stable yellow complex which fluoresces yellow-green when its solutions are irradiated with ultraviolet light. The system is evaluated as a basis for the quantitative determination of trace amounts of thorium, and some of the theoretical and mathematical relationships between fluorescence and light absorption are also included.
