| Résumé : |
Natural superfine needle down particles were successfully prepared on a self-made machine and applied to remove hazardous dye Vat Scarlet R from aqueous solution. The adsorbent was characterised by scanning electron microscopy and Fourier transform infrared spectroscopy. The effects of contact time, pH, adsorbent dosage, initial dye concentration, and temperature on dye adsorption on natural superfine needle down particles were discussed. Equilibrium adsorption studies revealed that the Langmuir isotherm model gave the best fit to experimental data, which indicates monolayer adsorption on a homogeneous surface. The monolayer adsorption capacity increased with increasing temperature in the range 298–318 K for Vat Scarlet R adsorption, and the maximum obtained adsorption capacity was 76.823 mg g−1 at 318 K. The present study suggested that natural superfine needle down particles could be used as a good and cheaper adsorbent for dye effluent treatment. |
