    Adsorption of Humic Acid From Aqueous Solution Onto Fe3o4 Coated Carbon: Effect of Temperature
    (2016-04-22) Zulfikar, Muhammad Ali; Suri, Fraulein Intan
    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.
