Rice Husk derived Activated Carbon for the Adsorption of Scarlet RR an Anionic Disperse Dye

Bioinspired mesoporous activated carbon was synthesized using rice husks. SEM (scanning electron microscopy), XRD (X-ray powder diffraction), FTIR (fourier transform infrared spectroscopy), and BET(Brunauer–Emmett–Teller) were used to detrmine the textural qualities and physicochemical properties of the produced activated carbon .Monolayer and multilayer isotherm models were evaluated to examine the adsorption investigations on hydrophobic Scarlet RR. The Langmuir adsorption isotherm best explained the results because the monolayer's adsorption capacity was 996 mg/g at adsorbent dosage of 1.5 g/L. The results suggested that bio-inspired activated carbon would work well as an adsorbent for dye removal from polluted water.
