“…In a spectrometric method a stabilized plasma-jet flame was used for the determination of aluminum in steel (176). ANTIMONY Solvent extraction of colored complexes was necessary in the spectrophotometric determination of antimony in steels using Crystal Violet (12), Brilliant Green (368), and Safranine T (413), and distillation separation as SbCl3 was necessary before photometric determination with methylene blue (86). For 0.001 to 0.065% antimony in iron ores rhodamine B was used (315).…”
