Removal of lead ions from aqueous solution by retorted shale
The equilibrium and kinetic properties of Pb2+ion adsorption by retorted shale (RS) have been investigated during a series of batchadsorption experiments. The effects of pH, contact time and adsorbate initial concentration were evaluated. The pseudo-second-order modelwas used to predict the rate con...

| Sumario: | The equilibrium and kinetic properties of Pb2+ion adsorption by retorted shale (RS) have been investigated during a series of batchadsorption experiments. The effects of pH, contact time and adsorbate initial concentration were evaluated. The pseudo-second-order modelwas used to predict the rate constants of adsorption system. Langmuir and Freundlich models were used to fit the equilibrium data, whichshowed that Langmuir best-fitted these data. Thermodynamic parameters of adsorption indicate spontaneous and endothermic nature of theprocess |
