Description
Summary:The study aimed to obtain of palm kernel shell activated carbon (PKSAC) potentially as an adsorbent for recovery of β-carotene from crude palm oil. Activation of palm kernel shell carbon was done chemically using phosphoric acid at impregnation ratio of 3 (ml/g) for 24 hours and carbonization at 500 °C for 30 min and 60 min called PKSAC30 and PKSAC60 respectively. The results showed that the yield of PKSAC30 and PKSAC60 were 48.82% and 47.67%, the surface area were 1665.823 and 1680.877 m2/g respectively, whereas surface area of decolorized activated charcoal (DAC) as control activated carbon was 1068.391 m2/g. PKSAC30 able to adsorb β-carotene in isopropyl alcohol at the equilibrium as much as 14.32 mg/g, while the DAC as much as 21.58 mg/g. Desorption of β-carotene from DAC using tetrahydrofuran reached 49.99%, while from PKSAC30 reached 28.30%.
