摘要：

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 (FUR) were used to characterize the adsorbent material, respectively. The effects of pH, adsorbent dose, initial dye concentration, temperature, and contact time on the adsorption capacity of DFS-4BS by NSDP were studied. The experimental adsorption data were well fitted by Langmuir adsorption isotherm and the maximum adsorption capacity of DFS-4BS by NSDP was found to be 120.34 mg/g at 45 degrees C, which was higher than other reported adsorbent. Overall, NSDP could be used as an effective and low-cost adsorbent to remove DFS-4BS from industrial wastewater.
