Eco-Friendly Cellulose/Polyaniline Sponge for Water Remediation

= 25 mg/L MO) after only 20 min. The experimental data were adjusted to different isotherm adsorption models; the best fit was obtained using the Halsey model. Furthermore, the adsorption performance of PANI-CS was studied in continuous mode using a bespoke adsorption column with recirculation. The results indicated that after 5 min of interaction time, 59% of the initial MO concentration (25 mg/L) was adsorbed. These results show the potential of PANI-CS as an inexpensive adsorbent for large-scale adsorption of dyes from aqueous media.
