Thermodynamics and Kinetics Studies of Mn (II) Removal from Aqueous Solution onto Powder Corn Cobs (PCC)
Abstract
In this work the potential use of powder corn cobs (PCC) for the removal of Mn (П) from aqueous solutions has been investigated. Experiment results indicate that the uptake of Mn (II) decreased with increasing temperature. The adsorption kinetic data indicate that the process was well described by a pseudo-second order model. Thermodynamic parameter data indicate that the process is exothermic in nature and the values of ΔH° and activation energy confirmed that Mn (II) adsorption by PCC could be attributed to a physical adsorption process.
