- Abstract
Aerogel composed of polyaniline/cellulose nanofiber (PANI/CNF) was synthesized by a two-step method and used as an adsorbent to remove Cr(VI) from wastewater in this study. Adsorption results showed that PANI/CNF aerogel adsorbent exhibited a high adsorption capacity of 298. 5 mg·g-1 for Cr(VI) (318 K, pH = 2. 0). Meanwhile, the adsorption process can be fitted well with the pseudo-second-order model and the Freundlich model. Moreover, the Cr(VI) removal efficiency of the adsorbent remained above 85% after ten recycling experiments, indicating that PANI/CNF aerogel had excellent stability and reusability. Therefore, PANI/CNF aerogel showed a potential application in the treatment of chromiumcontaining wastewater.
