v SUMMARY The shells of nypa (Nypa fruticans Wurmb.) used as an adsorbent because it had a 45.6% of cellulose, 23.5% of hemicellulose, and 19.4% of lignin. In this work, the adsorbent applied to adsorb of heavy metals ions. This study aims to determine the ability of activated carbon of nypa shells in absorbing lead (II) ions. Activated carbon of nypa shells made by carbonization at 500°C fo…
