Abstract

Activated carbon is a porous material that has a high surface area capable of adsorbing various substances. The process of making activated carbon uses palm oil shell biomass waste with a carbonization method and is activated using H₂SO₄. Activated carbon is used as an adsorbent in the Ammonia (NH₃) adsorption process. Variations in the adsorption process were used, namely, H₂SO₄ activation concentration (5, 10, 15 and 20%) and adsorption contact time for (15, 30, 45, and 60 minutes). The optimum adsorption capacity of 12.97% was shown in the activated carbon adsorbent activated by 20% H₂SO₄ with a contact time of 30 minutes. The optimum result of reducing the NH₃ concentration from 100 ppm to 50 ppm occurred at 15 and 20% activation with a contact time of 60 minutes. Variations in activation concentration and contact time affect the adsorption capacity so that NH3 can be absorbed by activated carbon.
