- 中文摘要: A very simple spectrophotometric method for simultaneous determination of aluminum(III) and iron(III) based on formation of their complexes with pyrocatechol violet (PCV) in micellar media, using the H-point standard addition method (HPSAM), is described. In micellar media, the metal complexes of Al-PCV and Fe-PCV are formed very fast. Formation of both of the complexes was complete within 5 min at pH 8.5. The linear ranges for aluminum and iron were 0.05-2.50 and 0.10-4.00 mg mL-1, respectively. The relative standard deviation (R.S.D.) for the simultaneous determination 0.40 mg mL-1 of Al(III) and 0.20 mg mL-1 of Fe(III) were 3.24% and 4.22%, respectively. Interference effects of common anions and cations were studied. The method was applied to simultaneous determination of Al(III) and Fe(III) in standard reference material and alloy samples.
