Abstract

Chemical impregnation with H2SO4 solution produces activated carbon from exhausted tea wastes. The adsorption behaviour of activated carbon towards Acid Blue 92 (acidic dye-AB92) is examined in this work. The research used the batch adsorption approach to investigate the impact of key factors such contact time, preliminary dye concentration, and temperature. To understand the reaction process, the kinetic data was performed using pseudo first order, second order, and elovich models.The pseudo second order kinetic mechanism was found to be appropriate for the materials based on the correlation coefficient value (R2). The Langmuir followed by Freundlich models were used to analyses the isotherm data. Thermodynamic parameters were determined as well. The results revealed that the prepared activated tea waste carbon from teawaste materials is a very effective adsorbent for AB92 adsorption.
