Abstract
This study aims to determine the ability of activated carbon from oil palm shell coated with magnetite (Fe3O4) (ACC-M) to adsorb Cu(II) ions in solution. Production of ACC-M adsorbent begins with the activation of oil palm shell carbon physically-by heating at a temperature of 700°C. Magnetite coating on activated carbon was done by adding Fe3+/ Fe2+ solution to the activated carbon suspension followed by adding NaOH solution to pH of 10. Characterization of ACC-M included surface morphology analysis with Scanning Electron Microscopy-Energy Dispersive-X Ray (SEM-EDX), surface area and pore diameter determination with the Brunauer-Emmett-Teller Surface Area Method (SBET). The adsorption test of the solution of Cu(II) ions by ACC-M adsorbent was carried out by batch method including a series of experiments, namely the effect of adsorbent dosage, determination of adsorption kinetics, and isotherm models. The result shows that in the use of 0.4 grams of ACC-M adsorbent at the interaction time of 60 minutes and pH of 5, the adsorbent are able to adsorb Cu(II) ions with the adsorption capacity of 99.60%. Thus, ACC-M adsorbent is a highly effective adsorbent to absorb Cu(II) ions in solution.
