Individual and mixed solutions of Ni, Pb and Cd with 5
different concentrations of 5, 10, 15, 30 and 100 mg/L
where prepared synthetically and in order to determine
the efficiency of teawaste in metal adsorption, the
experiments were performed using 3 different amounts
of adsorbent: 0.5, 1 and 1.5 g in single solution. The
procedure for first experiment was as follows: to 15
