Abstract：The adsorption behaviors of Cd(Ⅱ) and Pb(Ⅱ) on green tea and black tea in aqueous solution as well as the influences of time，acidity and temperature on the adsorption have been studied. It was found that Cd(Ⅱ) and Pb(Ⅱ) can been adsorbed strongly by green tea and black tea samples. The adsorption effects depend on the pH strongly when pH＜4. The recovery of Pb(Ⅱ) on tea samples is more than that of Cd(Ⅱ) when pH＜6 and it is opposite when pH＞6. It is difficult to elute Cd(Ⅱ) and Pb(Ⅱ) from tea samples by water at 25 ℃.
