dc.description.abstract | This study was aimed at the adsorption of Brilliant Green (BG) on hydrolyzed rice straw biochar, which was obtained from a lignocellulosic bioethanol process. Rice straw biochar (RBC) possessed surface properties such as a Brunauer-Emmett-Teller (BET) surface area of 232.31 m(2)/g, a total pore volume of 0.30 cm(3)/g, and an average pore width of 5.22 nm. Adsorption studies were carried out to investigate the effect of experimental factors such as pH (2-10), biochar dose (0.05-1.25 g/L), contact time (30480 min), and temperature (30 to -50 degrees C) on the adsorption of BG. The Langmuir isotherm (R-2 = 0.998) fitted well to the adsorption data for initial dye concentrations of 20-500 mg/L, implying that BG adsorption occurred in the form of a monolayer on RBC. Adsorption kinetics was well fitted by the pseudo-second order kinetic model (R-2 >= 0.988) for all tested dye concentrations. The thermodynamic study revealed that BG adsorption on RBC was spontaneous, favorable, and a physical process. The maximum adsorption capacity of RBC was found to be 111.11 mg/g. These results showed that RBC, prepared from the waste of the bioethanol process, can be effectively used as a promising cheap adsorbent to remove dyes from aqueous solution. This approach of product diversification (bioethanol along with biochar) may lead to a cost effective and cleaner production of bioethanol. | - |
