Kinetics of 18-carbon carboxylate adsorption at the fluorite surface

In this study the kinetics of oleate and linoleate adsorption at the fluorite surface have been examined, in-situ, by Fourier transform infrared internal reflection spectroscopy. Data obtained in this study show that the adsorption process is not controlled by convective diffusion. Other results from this study indicate that oleate adsorbs to approximately the same monolayer coverage level when given sufficient time over a variety of temperature and solution conditions. This study also shows that competitive anions such as OH-, CO32-, and F- can severely restrict the rate of oleate adsorption; furthermore, proper control of such species will result in maximum oleate adsorption kinetics.
