Ahmed A. Galhoum,Mohammad G. Mahfouz,Asem A. Atia,Sayed T. Abdel-Rehem,Nabawia A. Gomaa,Thierry Vincent,Eric Guibal +6 more
TL;DR: In this article, the effect of pH on sorption performance is first investigated before evaluating uptake kinetics and sorption isotherms, and metal desorption and sorbent recycling are finally carried out for five successive cycles of sorption/desorption.

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.
