Lead removal from aqueous solution by natural and pretreated clinoptilolite: adsorption equilibrium and kinetics.
TL;DR: Kinetic parameters; rate constants, equilibrium adsorption capacities and related coefficients for each kinetic model were evaluated according to relative errors and correlation coefficients and results show that best fitted kinetic models are obtained to be in the order: the pseudo-first order, the Pseudo-second order and Elovich equations.
