In addition, this research has compared the adsorption efficiency of lead adsorption with the lotus stalk charcoal, found that the concentration is 50 milligrams per liter. And the adsorbent amount of 0.25 grams of powder activated carbon was the most adsorption efficiency was 99.91 percent. Pellet activated carbon with the highest adsorption efficiency was 98.30 percent and lotus leaf charcoal had the most adsorption efficiency. The best lining is 99.78 percent.
