I-(2-Pyridylazo)-2-naphthol reacts with uranium to form a deep red precipitate in ammoniacal solutions. This can be extracted with chloroform if sodium chloride or sulfate is added and it has a maximum absorption at 560 m mu . The color is stable and follows Beer-s law. Trace amounts of uranium may be determined in the presence of many metals without prior separation if strong complexing agents. such as ethylenediaminetetraacetic acid (disodium salt) or cyanide. are added.
