ABSTRACT
Aluminium was determined by flow injection spectrofluorimetry at 510 nm after excitation at 396 nm following extraction of tetraphenylphosphonium aluminium(III) 8-hydroxyquinoline-5-sulphoxinate into chloroform. The effects of diverse ions and masking studies are reported. The system has been applied to the determination of aluminium in steels by the method of standard additions.
