A rapid spectrophotometric method for the determination of small amounts of aluminum in uranium metal and uranium compounds is described. The method makes use of the yellow-colored complex formed between aluminum and 8-hydroxyquinoline (oxine) at pH 9.5–10; the complex is extracted with carbon tetrachloride. Elements which interfere are extracted with 8-hydroxyquinaldine. The method is suitable for the determination of up to 0.1% aluminum.
