The Kinetics of Binding of Tris- (4;7- Dimethyl-1;10-Phenanthroline)Iron(II) Perchlorate with Sodium Dodecyl Sulphate

Latona D. F, Ige J, Soriyan O.

Abstract: The kinetics of binding of tris- (4; 7-dimethyl-1; 10-phenanthroline) iron (II) perchlorate with sodium dodecyl sulphate was investigated below the critical micelle concentration of the surfactant. The effects of additives like sodium benzoate; urea; H+ and OH- on the binding due to hydrophobic/electrostatic interaction was studied. The reaction was monitored under pseudo-first order kinetics with a unicam UV-visible spectrophotometer. The binding of phenanthroline iron (II) complex was demonstrated by hydrophobic effect due to the presence of the phenanthroline ligands and by electrostatic interaction due to the +2 charge on the complex. The reaction was complex independent. General invariance in free energy of activation showed same mechanism for the reaction.

Keywords: dimethyl 1-1, 10-phenanthroline, iron II
