主 题:Wastewater adsorption desorption thermo-kinetic modeling isotherms
摘 要:A coupled adsorption–desorption thermo-kinetic model is developed incorporating both adsorption and desorption reactions.A local pseudo-equilibrium condition at the interface of adsorbent and adsorbate bulk phases was used as isotherm equation which can even be applied for multi-pollutants *** developed model is then validated using collected experimental data of heavy metal ions(Pb,Cu,Cd,Zn,and Ni).Comparisons were made for a number of isotherm and kinetic models to examine the performance of the proposed *** developed model revealed desirable accuracy and superiority over other models in predicting the adsorption behavior and can be used for other systems of *** model correlates the adsorption kinetic with an R2 value of 0.9391 and desorption kinetic with an R2 value of *** application of the proposed model to any available adsorption datasets,the individual characteristics of adsorption and desorption can be determined.
