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.
