Adsorption of Humic Acid from Aqueous Solution onto PVDF Nanofiber: Effect of Temperature

Abstract:

The sorption of humic acid from aqueous solution onto polyvinyl difluoride nanofiber 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 (∆H) and entropy (∆S) of +16.32 kJ mol^-1 and +41.92 J mol^-1, respectively.
