In this study, the agricultural solid waste, natural down fibers were produced into superfine down particle (NSDP), which was used as a low-cost adsorbent for the removal of direct fast scarlet 4BS (DFS-4BS) from aqueous solution. Scanning electron microscopy (SEM), N 2 adsorption/desorption, and Fourier Transform infrared spectroscopy (FTIR) were used to characterize the adsorbent...
The diethylenetriamine (DETA)/polyacrylonitrile (PAN) composite nanofibers were prepared by using electrospinning technique. The surface morphology and chemical characterization of PAN/DETA composite nanofibers were investigated using scanning electron microscopy (SEM) and Fourier transform infrared (FTIR) spectroscopy. Releasing possibility of DETA from nanofibers was tested by total organic carbon...
