Effectiveness of activated carbon from rubber seed shell as adsorbent of liquid waste of heavy metal
Iron ORG GF BUCKWHEAT GROATS or Fe is classified as a metal that has low toxicity, but if the concentration exceeds the quality standard, it can potentially cause pollution to the environment.This study aims to make activated carbon from rubber seed coat shells as an adsorbent for artificial Fe liquid waste using Fe2(SO4)3.05 grams of activated car
