This project aims to test the efficiency of absorption of lead in solution of lead (II) nitrate by a performance comparison between tea waste bagasse pretreatment with sodium hydroxide 1.5 M, and tea waste is mixed with milk. cane pretreatment with sodium hydroxide 1.5 M, using a solution of lead (II) nitrate 0.5 M, 100 ml, the study found that tea waste efficiently absorb Slade (I. I) iodide is best. The amount of lead residue remaining 0.1116%, with tea as an adsorbent is the best test to check for factors that affect the adsorption process. The time is the time of exposure and the concentration of the solution. Lead (II) nitrate, initial results showed that the ability to absorb the solution. Lead (II) nitrate concentrations. 0.5 molar Best By touching the appropriate time is 1 hour 30 minutes.
