Activated charcoal of palm shell that activated with NaOH can be used as an adsorbent of heavy metal ions with quite high adsorption efficiency. In this research, i want to know the value of adsorption to a mixture of Zn2+ metal ions and Cr3+ metal ions. Activation using NaOH in this study aims to remove lignin levels from palm shells, also to expand porosity and increase active sites on palm s…
