Abstract:
The sorption of humic acid from aqueous solution onto Fe3O4 coated carbon
under the influence of temperature has been investigated. Batch adsorption
experiments were carried out using humic acid (HA) as an adsorbate. It was
observed that the amount of humic acid adsorbed increase with increasing
temperature. Thermodynamic parameters data indicated that the humic acid
adsorption was non-spontaneous and endothermic under the experimental
conditions, with the enthalpy (ΔH) and entropy (ΔS) of +29,44 J mol-1 and +74.96
J mol-1, respectively.
