The pure water used in industries creates wastewater which has a potential hazard to our health and environment because of introduction of various heavy metals in solid and liquid form. In this study removal of Nickel, Cadmium and Lead from industrial waste has been investigated by using tea-waste as an absorbent.This research is experimental type and the analyses are performed using different amount of absorbent in the solution with six different concentrations of each metal and its complex. Results indicate that the removal efficiency is maximum for Lead and is minimum for Cadmium. 905 of lead are removed by using 0.5g tea-waste and 100% by 1.5g tea-waste as sorbent for solutions having 5mL and 10mL concentration of lead. Whereas 1.5g tea waste can absorb 85% of 5mL nickel solution and 76% of 5mL cadmium solution.
