Abstract

The binding of ferrocyphen (Fe(C12H8N2)(CN)2) with sodium dodecylsulfate has been studied at various concentration of sodium dodecylsulfate as a function of aromatic counter ion (sodium benzoate) concentration. The unusual scatchard plot has been interpreted using binding capacity concept. The results represents two binding set for all the studied conditions. The value of Hill equation parameter have been estimated and used for calculation of intrinsic Gibbs free energy of binding.
 

Key words: Surfactant, ferrocyphen, ion- pair, counter ion, capacity concept.
