The results showed that the adsorption efficiency of Lead at concentrations of 30, 40 and 50 milligrams per liter. The adsorbent amount of 0.25 grams has the best adsorption efficiency. The Granular activated carbon has the adsorption efficiency percent of 96.05, 96.29 and 98.30 respectively, and the powdered activated carbon has the adsorption efficiency percent of 99.88, 99.69 and 99.91 respectively.
