Efforts to deal with waste using the adsorption method showed effective results. However, it was discussed of the sorbent after the remediation process is cumbersome. An alternative to overcome this problem can be done by fixing the adsorbent into a solid form consisting of a porous polymer without changing its chemical affinity with metal ions. In this study, the adsorbent used was bioelastomeric containing activated charcoal from palm shell waste and elastomeric, which would then be contacted with Hg 2+ metal ions. The process variable in this study was the composition of heavy metal Hg 2+ 8, 12, 16, 20, and 24 mg/L with the contact time until it reached equilibrium. Based on the calculation, the palm shell bioelastomeric used three adsorption isotherm models, Freundlich isotherm (R 2 = 0.991), Langmuir isotherm (R 2 = 0.967) and Dubinin-Radushkevich isotherm (R 2 = 0,871). The results showed that the efficiency of adsorption of heavy metal Hg 2+ with bioelastomeric palm shell was almost close to 100%. In conclusion, palm shell bioelastomeric can be a potential adsorbent with a high heavy metal removal ability.
