TLDR
It was observed that the rate of dye adsorption follows pseudo-second-order model for the dye concentration range studied in the present case and the estimated values of DeltaH0 and DeltaS0 both show the negative sign, which indicate that the Adsorption process is exothermic and the dye molecules are organized on the kaolin surface in less randomly fashion than in solution.About:

Kinetics of Adsorption on Carbon from Solution
Walter J. Weber,J. C. Morris +1 more
TL;DR: In this paper, it was shown that the rate of adsorption of persistent organic compounds on granular carbon is quite low and the rate is partially a function of the pore size distribution of the adsorbent, of the molecular size and configuration of the solute, and of the relative electrokinetic properties of adsorbate and adsorbents.
