All rights reserved.The potential of nanofiber membrane functionalized with molecularly imprinted polymers (NFMIPs) prepared by the electrospinning technique for the humic acid (HA) removal from peat water was investigated. In this process, preparation of NFMIPs comprised of two steps. The first step was to synthesize fabrication of polyvinylidene fluoride (PVDF) nanofiber membrane as support and the second step was to synthesize imprinted polymer on the surface of PVDF nanofiber membrane. The prepared NFMIPs were characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, transmission electron microscopy, Brunauer–Emmett–Teller and thermogravimetric analysis. Finally, the adsorption experiments were carried out to investigate the effect of different adsorption parameters, such as contact time, adsorbent dosage, pH and temperatures in a batch system. The NFMIPs materials were then used for HA adsorption from peat water using batch adsorption technique. Adsorption was best described by Langmuir isotherm and adsorption capacity was found to be 153.3 mg/g. From the kinetic studies, the adsorption of HA onto NFMIPs materials followed the pseudo-second-order kinetic model with a rate constant in the range of 0.032–0.104 g/mg min. The adsorption equilibrium was achieved at about 90 min. The amount adsorbed increased with increasing adsorbent dosage and the temperature, otherwise decreased with increasing peat water pH (from 2 to 10).[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Electrospinning,Humic acid,Nanofiber,Peat water[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]The authors are very grateful to Research, Technology and Higher Education Ministry for their financial support through Riset Unggulan Perguruan Tinggi 2016/2017.
