Abstract
The interactions of scandium and chromazurol S with cation active tensides were studied, i.e. with cetylmethylammonium, carbathoxypentadecyltrimethylammonium and cetylpyridinium bromide. The formation of a ternary negatively charged complex with component ratio 1 : 2 : 2 was confirmed. The ternary complex can be employed for very sensitive spectrophotometric determination of 0.04-0.4μg of scandium in 1 ml of analyzed solution.
