Abstract
In this research, the synthesis and characterization of activated carbon from rubber fruit shells was carried out through physical-chemical activation (RS-AC) followed by magnetite coating to produce magnetite-physical-chemical activated carbon (RS-MAC) as a Comassie Brilliant Blue (CBB) adsorbent. Activation of carbon was carried out physically by heating at 700 ℃ and chemically using a 10% H3PO4 solution as activating agent. The magnetite coating was carried out by the co-precipitation method. Characterization of RS-AC and RS-MAC were carried out using XRD to identify the crystallinity level of adsorbent and SEM-EDX to determine surface morphology and identify elemental composition. The result show that RS-MAC had the maximum sorption for CBB (91.98%) at acidic condition (pH 3) and contact time of 90 minutes. Keywords: activated carbon, rubber fruit shells, magnetite coating, adsorption, Brilliant Blu
