Abstract
The diffusion dynamics of a Yukawa fluid confined in an attractive planar slit pore was studied by solving the Smoluchowski/Hypernneted-chain equation for the mean first passage times. We show how the time it takes for a particle to get adsorbed at the wall surface is modulated by the effective potential barrier originated by the fluid local density profile. The effect of wetting layering on the apparent constant for the transverse diffusion towards an attractive pore wall is evaluated.
