Sodium Laurel sulfate (SLS) is an important anionic surfactant used in many detergent products. It is adsorbed on the surface of dishes during the process of cleaning. In this project the kinetics and thermodynamics of adsorption of SLS on aluminum surface were studied by using an ion mobility spectrometry (IMS) as detector. In this method aluminum surface was put in contact with the solution of SLS. After drying, the adsorbed SLS was measured by thermal desorption IMS. To study the kinetics of adsorption, aluminum surface was put in an SLS solution with defined concentration, for a given time. Simple Langmuir model was used to obtain kinetics properties of SLS adsorption. We found that a simple model would not describe the data. The time profile of the adsorption was a convolution of a fast and a slow rising exponential function. Thus, the kinetics of adsorption of SLS on Al surface best fitted to a two sites model. In this model, two different sites with different adsorption rate constants, k 1 and k 2 were considered. k 2 corresponds the to sites that are more kinetically favored for SLS adsorption, and k 1 corresponds to sites that less appropriate for adsorption. The desorption process was also studied by contacting saturated surface with pure water for given times. The desorption kinetics data also indicated that two different sites were involved. Microscopic image confirmed micelle formation in some parts of the surface. The effect of temperature on desorption reached the conclusion that temperature causes the desorption rate to be increased. The adsorption isotherm was also studied and revealed that SLS followed a multi region model. The experimental data fitted into the Langmuir isotherm and the enthalpy of adsorption was calculated through van’t Hoff equation. The adsorption enthalpy was obtained to be -2.19 (kJ/mol).
