RESULTS AND DISCUSSIONS
The study depicts about efficiency of absorption of Ni, Cd and Pb by tea-waste. It is found that tea-waste is one of
the best absorbent for lead and it depends mainly on time and amount of initial concentration of metal in source.
By comparison of the result we conclude that the absorption efficiency is dependent on type of metal i.e. if lead is
absorbed 94% than Ni is 74% and Cd 58% in same concentration.
