Abstract: Phenol compounds found in wastewaters of various industries such as petroleum refining, coal conversion, plastic, textiles, iron and steel manufacturing units. Remediation of phenols and its derivatives from contaminated water before discharging is essential, as they are toxic for aquatic organisms. This work is an attempt to remove phenol from aqueous solution applying the adsorption technique using locally available and eco-friendly tea waste adsorbent. The batch adsorption experiment was performed on different concentrations. Langmuir and Freundlich isotherms were applied to confirm the adsorption model. The data obtained found to be best fitted to the Langmuir isotherm. The kinetic study for the adsorption process were performed by checking various models and the data obtained show that the pseudo-second-order model fit well for both 8-HQ treated and untreated powdered tea waste adsorbent.
