In studies of the highly sensitive reactions between some polyvalent metal ions, chromeazurol S and cetyltrimethylammonium bromide, it was found that thorium also forms a pure blue complex in aqueous solution. An investigation of the properties of this ternary, water-soluble thorium complex is being made because of its very high molar absorptivity (over 10/sup 5/), Since very sensitive reactions are important in trace analysis, a new possibility to determine thorium spectrophotometrically in a normal aqueous solution is suggegted.
