Kinetics and thermodynamics of the phosphine adsorption on the modified activated carbon

Bingnan REN

Frontiers of Chemical Science and Engineering 2011, Volume 5, Issue 2, Pages 203-208 doi: 10.1007/s11705-010-0571-0

Abstract: been explained for the adsorption process of PH .The thermodynamic properties including PH adsorption isotherm and adsorption heat were separately investigatedThe adsorption capacity reached the maximum at 70°C.Then with increasing temperature, chemical adsorption gradually dominated in the adsorption process.The adsorption capacity decreased at above 70°C is due to the exothermic effects in the process of adsorption
