Three theoretical kinetic models were used to analyze the experimental results: the pseudo-first order kinetic model, the pseudo-second order kinetic model and the Elovich kinetic model. The results showed that the pseudo-second order kinetic model is the best fit for the analyzed data.ensunflower hullscopper ionskineticconferenceObject
