I am specifically trying to explain why adsorption capacity at equilibrium (qe) is higher with an increase in the initial contaminant concentrations. My plot of Ct/C0 with varying concentrations looks the opposite of what it should look like and I need to be able to explain it (why I need this plot at all is a long story).
Any links to references or examples would be greatly appreciated.
As the concentration increase, there is a higher chance that molecules collide/contact by the adsorbent surface, as a result of a higher mass transfer from the solution to the adsorbent Eq increases.

Ct/Co is not a good measure of the adsorption progress due to the difficulty in comparing these curves due to the rate of the phenomenon. Ce increases but only up to the limit determined by the mass of adsorbent used or its capacity. Regards,
