| Abstract: |
| The adsorption kinetics of Pb, Cu and Cd on hydrous ferrk oxide (HFO) has been approached in tthe simulated environmental conditions of the Changjiang Estuary.The forward adsorption rate constants of different systems under different temperatures have been determined, and the activation energies of the adsorption for Pb and Cu evaluated (Pb=7 kcal/mol, Cu=11 kcal/mol).The results show that Pb and Cu are strongly adsorbed by HFO; the order of their adsorption rate is found to be Pb ≥ Cu ≥ Cd, which follows thte order of their theonody-namic equilibrium constants.It has been demonstrated that the surface exchange-adsorption is the determining step of the solid-liquid interface process.The field investigation results are theoretically explained by the kinetic mechanism. |
