  1. In situ spectroscopic studies of the behavior of polyelectrolyte/surfactant mixtures at the water/TiO2 interface using attenuated total internal reflection Fourier transform infrared spectroscopy (ATR-FTIR) and multivariate least squares data analysis. TiO2 TiO2 TiO2 Dr. Dion Rivera Department of Chemistry, Central Washington University, Ellensburg, WA Below are results of multivariate analysis of UV-Vis spectroscopic data showing the concentrations of three species in solution as surfactant is added to the solution. The cartoon in the captions below indicates the point at which the polyelectrolyte /surfactant complex is no longer in solution. These solution phase results agree with our ATR-FTIR results that show the polyelectrolyte/surfactant complexes interacting with the TiO2 at similar mol ratios of polyelectrolyte to surfactant. Future work will involve understanding the behavior of the polyelectrolyte/surfactant complex at elevated temperature using both ATR-FTIR and UV-Vis.
