Use of Humic Acid-based Nanofibers for Dye Removal and Transport
MetadataShow full item record
A highly efficient nanofibrous adsorbent was prepared by using a mixture of humic acid (HA) and polyacrylonitrile (PAN) in DMF via electrospinning process, and the obtained nanofibrous adsorbent (PAN-HA) was used in copper removal. Owing to the incorporation of functional groups of HA, PAN nanofiber was turned into a material (PAN-HA) exhibiting anionic and cationic dye transfer. The prepared nanofiber mat was found to exhibit a suitable morphology according to the results of scanning electron microscopy, SEM, images. In this study, the removal and transport of HA-doped PAN nanofibers at different ratios (0-100%) at different pH and concentrations of methyl oranj, congo red, rodamin B and navy blue are carried out in a special membrane system. The results were evaluated in the design expert program.
