: Numerous Industries discharge their waste water comprise of heavy metal into the water bodies. Water contamination by heavy metals is a major environmental problem because to their acute toxicity. Many investigations have been performed to expel heavy metals using diverse techniques. However, Adsorption method is considered as one of the finest method as it is cost effective, efficient according to many studies. Several adsorbents have been utilized to remove different type of heavy metal ions from wastewater. For this research, Tea waste is used as an adsorbent for the removal of Cu from constituted waste water. Batch experiment was directed to govern optimum condition. Effect of parameter like pH, adsorbent dose, contact time and initial metal ion concentration were also determined. The optimum condition obtained is pH 5, Contact time 120 minute and initial concentration of 10ppm. The maximum removal of Cu by tea waste 91 % at an adsorbent dose of 0.5 gram /100 ml. The equilibrium data obtained from this study was fitted to various isotherm models and the Freundlich model with correlation coefficient R2 = 0.99 was seen to be the best fitted model. The adsorption kinetics uptake for Cu (II) was examined by the pseudo-first-order, pseudo-second-order and it was revealed that the process follow a pseudo second with correlation coefficient R2 = 0.99 for Cu by utilizing tea waste.
