AbstractA method is described by which a large range of aluminum concentrations may be determined speedily and with approximately +/-5 percent accuracy for samples containing less than 1.0 percent aluminum. Samples are taken into solution and impurities precipitated with sodium hydroxide. An aliquot containing the soluble sodium aluminate is adjusted to pH 4.6, 8-hydroxyquinoline is added and the complex aluminum 8-hydroxyquinolate extracted with chloroform and measured fluorimetrically at 560 mu. Various materials containing aluminum such as iron, steel, ores, aluminum powder and base metal alloys varying in aluminum content from 0.001 percent to 99.0 percent have been determined using a dilution technique. The fluorescent procedure has proved superior to gravimetric and colorimetric methods especially for low aluminum values in the presence of iron or phosphates.
