Abstract:
An assessment of the ability of a micellar surface to bind different metal ions using molecular simulation is presented in this study. Sodium dodecyl sulfate (SDS) is considered as the anionic surfactant. Various relevant characteristics of SDS-metal ion systems are estimated to quantify preferential binding of metal ions. These are electrostatic energy, total potential energy of the system, radial distribution function, and entropy and free energy change of the system. By examining these parameters, the relative extents of binding of different metal ions to the micellar surface are assessed.
