Spectrophotometric Determination of Kinetic Constants of Fe (III)-Amines’s Charge Transfere Complexes
نویسندگان
چکیده
Using UV-visible spectrophotometric data of (1:1), electron donor-acceptor complexes (AD1, AD2 and AD3) have been investigated. The complexes concerned are n-butyl amine (D1) and cyclohexyl amine (D2) and phenyl hydrazine (D3) as electron donors with iron (III) ion as an electron acceptor (A) in methanol at 25°C. The values of formation constant (kAD), molar extinction coefficient (eAD), and absorption band energy of complexes were estimated. The ionization potential of the donors ID, were calculated from the complex band energies. The kinetics of the above association and reverse reactions were studied and some kinetic parameters have been estimated.
