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.

Sorption of dye from aqueous solution by peat
Yuh-Shan Ho,Gordon McKay +1 more
TL;DR: In this paper, the sorption of two dyes, namely Basic Blue 69 and Acid Blue 25 onto peat has been studied in terms of pseudo-second order and first order mechanisms for chemical sorption as well as an intraparticle diffusion mechanism process.
