Abstract: | A spectrofluorimetric method, based on the formation of a fluorescent complex with salicyladehyde carbohydrazone, is optimized for the determination of thorium (20–800 μg l?1) at “pH” 1.3–1.7. The relative standard deviation is 2.7% for 100 μg Th l?1. The method is applied to synthetic mixtures containing various amounts of thorium and to the determination of thorium in monazite samples. |
