Abstract
In the present study, bioremediation of Basic Violet 03 is examined using biochar derived from agricultural wastes. The pyrolytic studies revealed that ideal temperature for maximum yield of biochar derived from Coconut Shell (CSB), Ground nut Shell (GnSB) and Rice Husk (RHB) was obtained as 400 °C, 350 °C and 300 °C respectively. Further from the batch mode of operations, it was concluded that the optimum conditions of biochar dose, pH, temperature and initial concentration are 4 g/L, 8, 40 °C and 75 mg/L with a maximum uptake of 15.79 mg/g, 17.28 mg/g, and 12.64 mg/g for CSB, GnSB and RHB. The adsorption isotherm studies concluded that the three-parameter Sips model was obtained to be the best fit with a maximum correlation coefficient (R2) of 0.9937, 0.9935 and 0.9965. The pseudo second order kinetic model was found to well represent the experimental kinetic data. The characterization results of biochar through SEM, EDX and FTIR revealed that there was a strong binding capacity of adsorbent was observed before and after adsorption process. The promising results concluded that biochar derived from agricultural wastes can potentially be utilized for the removal of cationic dyes.
