Interactional Study Of A Polymeric Organotin Complex In Micellar Media

In this manuscript, a study on interactions of a polymeric derivative of Tributyltin(IV) with [(2-Methylpropanoyl)amino]propanoic acid (TMP) in micellar media is presented. The study was conducted using two surfactants viz. Sodium 2-ethylhexylsulphate (SES) and Cetyltrimethylammonium bromide (CTAB). The solubilization parameters in terms of partition constant (K-c), partition coefficient (K-x), binding constant (K-b), Gibb's free energy of partition (Delta G(p)), and binding (Delta G(b)) were investigated by UV-Visible spectrophotometer. The estimation of micellization thermodynamics including entropy (Delta S-m), enthalpy (Delta H-m), and Gibb's free energy (Delta G(m)) were determined conductometrically. The compound showed more interaction with the cationic surfactant as compared to anionic participating surfactant due to comparative electrostatic interactions. The partition coefficient (K-x) in the micellar media of CTAB was significantly higher (4.22 x 10(7)) than SES media (1.33 x 10(5)). The Gibb's free energies of partition. Binding and micellization were higher in CTAB as compared to SES.
