Polycomponent Analysis of Metal Ions by 2 (2′ Imidazolylazo)Phenol 4 Sulfonic Acid

DAVUT·Ismail\ LIU Mi\ ZHAO Fenglin\ TONG Shenyang (College of Chemistry and Molecular Engineering, Peking University, Beijing, 100871)  
The reaction of 2 (2′ imidazolylazo)phenol 4 sulfonic acid(IAP 4S) with Cu(Ⅱ), Zn(Ⅱ) and Fe(Ⅲ) has been studied.The optimum pH ranges for the complex reaction are 5 ̄11, 5 ̄11 and 5 ̄7,respectively.The reaction is completed within 2 min at room temperature.Beer′s law is obeyed in the range of 0 ̄ 3 5μg/mL for Cu(Ⅱ),0 ̄ 4 0μg/mL for Zn(Ⅱ),0 ̄ 3 5μg/mL for Fe(Ⅲ) , and the apparent molar absorptivities of the complexes are 2 28×10 4,2 11×10 4 and 1 41× 10 4L/mol·cm ,respectively.Three components in the synthetic mixed solutions have been determined by Beckman DU 7 UV VIS spectrophotometer with polycomponent function.The results are satisfactory.
