Abstract—Humic acid (HA) is generally considered as one of ubiquitous pollutants in surface and ground water. In this study, the sorption of natural organic matter from water onto polyvinyl difluoride (PVDF) nanofiber under the influence of temperature has been investigated. The adsorption behaviors of the adsorbents for HA were investigated using batch experiments and adsorption kinetic tests. It was observed that the amount of HA adsorp increase with increasing temperature. The adsorption kinetic data of HA onto PVDF nanofiber was well described by a pseudo-second order model, with the kinetic constants in the range of 0.09 – 0.12 g mg

-1. From the intra-particle diffusion and Boyd kinetic models indicated that the HA adsorption process may be controlled by the intra-particle diffusion.
