To this end, we examined kinetic, equilibrium and thermodynamic aspects of the process. This paper reports the kinetics results. The experimental results indicate that the process was first order in C and the overall process was assumed to involve a single, reversible adsorption–desorption process obeying a kinetic law postulated by us}, publisher = {Elsevier}, title = {Interactions of xanthines with activated carbon I.
