This project aimed to study the potential of lead adsorption in aqueous solution Pb(NO3)2 by comparison the efficiency of waste tea, using 1.5 molar NaOH-treated bagasse,waste tea mix using 1.5 molarNaOH-treated bagasse by using solution Pb(NO3)2 concentration 0.5 molar volume 100 milliliter. The results revealed that have efficiency adsorption iswaste teaby waste tea. Batch experiment was carried out to investigate the effect of experimental parameters such as contact time and initial lead concentration. The findings found that increase an adsorbing potential on the initial lead concentration 0.5 molar with the optimal contact time at 1 hour 30 minutes.
