Fixed bed column adsorption of ACID Yellow 17 dye onto Tamarind Seed Powder

The intention of this study was to explore the efficacy and feasibility for Acid Yellow 17 adsorption onto fixed bed column of Tamarind Seed Powder. The effect of various parameters like flow rate, initial concentration of dye, bed height, and pH were exploited in this study. The Thomas, YoonNelson, Bed Depth Service Time (BDST), and Adams and Bohart model were analysed to evaluate the column adsorption performance. The adsorption capacity, rate constant and correlation coefficient associated to each model for column adsorption was calculated and mentioned. The adsorption capacity increases with increasing initial dye concentration and bed height and decreasing flow rate. The maximum adsorption capacity related to Adams and Bohart model was found to be 978.5?mg/g at initial concentration of 50?ppm at constant flow rate of 15?mL/min, bed height of 15?cm, and pH 7.
