Abstract
The current study estimates the feasibility of modified rice husk (MRH) in eliminating phenol and cyanide from binary aqueous solution through packed bed column studies. The influence of varying initial concentration, flow rate, and bed depth on the performance of packed column was examined. The experimental data for the packed bed column were applied in different kinetic model such as the Thomas, Adams–Bohart, Yoon–Nelson, and Wolborska model to calculate the breakthrough curve and to define the representative parameters of the packed bed column beneficial for scheming large-scale column studies. The Thomas model is to be found best for phenol, whereas Yoon–Nelson Model provided good agreement with experimental data (R2 > 0.85) for both phenol and cyanide. This model was designed to calculate the 50% breakthrough time attained by the packed bed column system and provided the predictable breakthrough time for the packed bed columns that were not exhausted throughout the process. Average relative error was applied to estimate the characteristics of the predicted and experimental values under the corresponding models to observe the best fit model. The MRH packed bed column could be effectively used up to six cycles of adsorption/desorption for the elimination of phenol and cyanide, respectively.
