The method is described of a spectrophotometric determination of U(VI) based on the extraction of its complex thiocyanate anion with a chloroform solution of 1-ethoxycarbonylpentadecyltrimethylammonium. The method is rapid and affords reliable results; 0.2 to 5 μg of uranium can be determined in 1 ml of organic phase. Combination with a preliminary separation treatment is feasible.
